Pete Bacon Darwin 7186f9c016 refactor(ivy): implement a virtual file-system layer in ngtsc + ngcc (#30921)
To improve cross platform support, all file access (and path manipulation)
is now done through a well known interface (`FileSystem`).

For testing a number of `MockFileSystem` implementations are provided.
These provide an in-memory file-system which emulates operating systems
like OS/X, Unix and Windows.

The current file system is always available via the static method,
`FileSystem.getFileSystem()`. This is also used by a number of static
methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass
`FileSystem` objects around all the time. The result of this is that one
must be careful to ensure that the file-system has been initialized before
using any of these static methods. To prevent this happening accidentally
the current file system always starts out as an instance of `InvalidFileSystem`,
which will throw an error if any of its methods are called.

You can set the current file-system by calling `FileSystem.setFileSystem()`.
During testing you can call the helper function `initMockFileSystem(os)`
which takes a string name of the OS to emulate, and will also monkey-patch
aspects of the TypeScript library to ensure that TS is also using the
current file-system.

Finally there is the `NgtscCompilerHost` to be used for any TypeScript
compilation, which uses a given file-system.

All tests that interact with the file-system should be tested against each
of the mock file-systems. A series of helpers have been provided to support
such tests:

* `runInEachFileSystem()` - wrap your tests in this helper to run all the
wrapped tests in each of the mock file-systems.
* `addTestFilesToFileSystem()` - use this to add files and their contents
to the mock file system for testing.
* `loadTestFilesFromDisk()` - use this to load a mirror image of files on
disk into the in-memory mock file-system.
* `loadFakeCore()` - use this to load a fake version of `@angular/core`
into the mock file-system.

All ngcc and ngtsc source and tests now use this virtual file-system setup.

crisbeto 4b16d98955 perf(ivy): chain multiple property instructions (#31078)
Currently each property binding generates an instruction like this:

```
property('prop1', ctx.value1);
property('prop2', ctx.value2);
```

The problem is that we're repeating the call to `property` for each of the properties. Since the `property` instruction returns itself, we can chain all of the calls which is more compact and it looks like this:

```
property('prop1', ctx.value1)('prop2', ctx.value2);
```

These changes implement the chaining behavior for regular property bindings and for synthetic ones, however interpolated ones are still handled like before, because they use a separate instruction.

JoostK 6fbfb5a159 feat(ivy): ngcc - recognize static properties on the outer symbol in ES5 (#30795)
Packages that have been compiled using an older version of TypeScript
can have their decorators at the top-level of the ES5 bundles, instead
of inside the IIFE that is emitted for the class. Before this change,
ngcc only took static property assignments inside the IIFE into account,
therefore missing the decorators that were assigned at the top-level.

This commit extends the ES5 host to look for static properties in two
places. Testcases for all bundle formats that contain ES5 have been added
to ensure that this works in the various flavours.

A patch is included to support UMD bundles. The UMD factory affects how
TypeScripts binds the static properties to symbols, see the docblock of
the patch function for more details.

Paul Gschwendtner 58be2ff884 fix(ivy): unable to bind to implicit receiver in embedded views (#30897)
To provide some context: The implicit receiver is part of the
parsed Angular template AST. Any property reads in bindings,
interpolations etc. read from a given object (usually the component
instance). In that case there is an _implicit_ receiver which can also
be specified explicitly by just using `this`.

e.g.

```html
<ng-template>{{this.myProperty}}</ng-template>
```

This works as expected in Ivy and View Engine, but breaks in case the
implicit receiver is not used for property reads. For example:

```html
<my-dir [myFn]="greetFn.bind(this)"></my-dir>
```

In that case the `this` will not be properly translated into the generated
template function code because the Ivy compiler currently always treats
the `ctx` variable as the implicit receiver. This is **not correct** and breaks
compatibility with View Engine. Rather we need to ensure that we retrieve
the root context for the standalone implicit receiver similar to how it works
for property reads (as seen in the example above with `this.myProperty`)

Note that this requires some small changes to the `expression_converter`
because we only want to generate the `eenextContent()` instruction if the
implicit receiver is _actually_ used/needed. View Engine determines if that is the case by recursively walking through the converted output AST and
checking for usages of the `o.variable('_co')` variable ([see here][ve_check]). This would work too for Ivy, but involves most likely more code duplication
since templates are isolated in different functions and it another pass
through the output AST for every template expression.

Paul Gschwendtner 2b4d5c7548 fix(ivy): ngcc should process undecorated base classes (#30821)
Currently undecorated classes are intentionally not processed
with ngcc. This is causing unexpected behavior because decorator
handlers such as `base_def.ts` are specifically interested in class
definitions without top-level decorators, so that the base definition
can be generated if there are Angular-specific class members.

In order to ensure that undecorated base-classes work as expected
with Ivy, we need to run the decorator handlers for all top-level
class declarations (not only for those with decorators). This is similar
to when `ngtsc` runs decorator handlers when analyzing source-files.

JoostK 9d9c9e43e5 feat(ivy): static evaluation of TypeScript's `__spread` helper (#30492)
The usage of array spread syntax in source code may be downleveled to a
call to TypeScript's `__spread` helper function from `tslib`, depending
on the options `downlevelIteration` and `emitHelpers`. This proves
problematic for ngcc when it is processing ES5 formats, as the static
evaluator won't be able to interpret those calls.

A custom foreign function resolver is not sufficient in this case, as
`tslib` may be emitted into the library code itself. In that case, a
helper function can be resolved to an actual function with body, such
that it won't be considered as foreign function. Instead, a reflection
host can now indicate that the definition of a function corresponds with
a certain TypeScript helper, such that it becomes statically evaluable
in ngtsc.

Paul Gschwendtner aca339e864 fix(ivy): unable to project into multiple slots with default selector (#30561)
With View engine it was possible to declare multiple projection
definitions and to programmatically project nodes into the slots.

e.g.

```html
<ng-content></ng-content>
<ng-content></ng-content>
```

Using `ViewContainerRef#createComponent` allowed projecting
nodes into one of the projection defs (through index)

This no longer works with Ivy as the `projectionDef` instruction only
retrieves a list of selectors instead of also retrieving entries for
reserved projection slots which appear when using the default
selector multiple times (as seen above).

In order to fix this issue, the Ivy compiler now passes all
projection slots to the `projectionDef` instruction. Meaning that
there can be multiple projection slots with the same wildcard
selector. This allows multi-slot projection as seen in the
example above, and it also allows us to match the multi-slot node
projection order from View Engine (to avoid breaking changes).

It basically ensures that Ivy fully matches the View Engine behavior
except of a very small edge case that has already been discussed
in FW-886 (with the conclusion of working as intended).

Alex Rickabaugh b61784948a fix(ivy): template inputs/outputs should not be bound in template scope (#30669)
The R3TargetBinder "binds" an Angular template AST, computing semantic
information regarding the template and making it accessible.

One of the binding passes previously had a bug, where for the following
template:

<div *ngIf="foo as foo"></div>

which desugars to:

<ng-template ngIf [ngIf]="foo" let-foo="ngIf">
  <div></div>
</ng-template>

would have the `[ngIf]` binding processed twice - in both the scope which
contains the `<ng-template>` and the scope inside the template. The bug
arises because during the latter, `foo` is a variable defined by `let-foo`,
and so the R3TargetBinder would incorrectly learn that `foo` inside `[ngIf]`
maps to that variable.

This commit fixes the bug by only processing inputs, outputs, and
templateAttrs from `Template`s in the outer scope.

Olivier Combe 5e0f982961 feat(ivy): use i18n locale data to determine the plural form of ICU expressions (#29249)
Plural ICU expressions depend on the locale (different languages have different plural forms). Until now the locale was hard coded as `en-US`.
For compatibility reasons, if you use ivy with AOT and bootstrap your app with `bootstrapModule` then the `LOCALE_ID` token will be set automatically for ivy, which is then used to get the correct plural form.
If you use JIT, you need to define the `LOCALE_ID` provider on the module that you bootstrap.
For `TestBed` you can use either `configureTestingModule` or `overrideProvider` to define that provider.
If you don't use the compat mode and start your app with `renderComponent` you need to call `ɵsetLocaleId` manually to define the `LOCALE_ID` before bootstrap. We expect this to change once we start adding the new i18n APIs, so don't rely on this function (there's a reason why it's a private export).

Alex Rickabaugh 84dd2679a9 fix(core): require 'static' flag on queries in typings (#30639)
This commit makes the static flag on @ViewChild and @ContentChild required.

BREAKING CHANGE:

In Angular version 8, it's required that all @ViewChild and @ContentChild
queries have a 'static' flag specifying whether the query is 'static' or
'dynamic'. The compiler previously sorted queries automatically, but in
8.0 developers are required to explicitly specify which behavior is wanted.
This is a temporary requirement as part of a migration; see
https://angular.io/guide/static-query-migration for more details.

@ViewChildren and @ContentChildren queries are always dynamic, and so are
unaffected.

Previously we defensively wrapped expressions in case they ran afoul of

Call(Ternary(a, b, c)), but might result in printed code of:

```
a ? b : c()
```

Whereas the actual structure we meant to generate is:

```
(a ? b : c)()

However the TypeScript renderer appears to be clever enough to provide
parenthesis as necessary.

JoostK 0937062a64 fix(ivy): type-checking should infer string type for interpolations (#30177)
Previously, interpolations were generated into TCBs as a comma-separated
list of expressions, letting TypeScript infer the type of the expression
as the type of the last expression in the chain. This is undesirable, as
interpolations always result in a string type at runtime. Therefore,
type-checking of bindings such as `<img src="{{ link }}"/>` where `link`
is an object would incorrectly report a type-error.

This commit adjusts the emitted TCB code for interpolations, where a
chain of string concatenations is emitted, starting with the empty string.
This ensures that the inferred type of the interpolation is of type string.

JoostK e9ead2bc09 feat(ivy): more accurate type narrowing for `ngIf` directive (#30248)
A structural directive can specify a template guard for an input, such that
the type of that input's binding can be narrowed based on the guard's return
type. Previously, such template guards could only be methods, of which an
invocation would be inserted into the type-check block (TCB). For `NgIf`,
the template guard narrowed the type of its expression to be `NonNullable`
using the following declaration:

```typescript
export declare class NgIf {
  static ngTemplateGuard_ngIf<E>(dir: NgIf, expr: E): expr is NonNullable<E>
}
```

This works fine for usages such as `*ngIf="person"` but starts to introduce
false-positives when e.g. an explicit non-null check like
`*ngIf="person !== null"` is used, as the method invocation in the TCB
would not have the desired effect of narrowing `person` to become
non-nullable:

```typescript
if (NgIf.ngTemplateGuard_ngIf(directive, ctx.person !== null)) {
  // Usages of `ctx.person` within this block would
  // not have been narrowed to be non-nullable.
}
```

This commit introduces a new strategy for template guards to allow for the
binding expression itself to be used as template guard in the TCB. Now,
the TCB generated for `*ngIf="person !== null"` would look as follows:

```typescript
if (ctx.person !== null) {
  // This time `ctx.person` will successfully have
  // been narrowed to be non-nullable.
}
```

This strategy can be activated by declaring the template guard as a
property declaration with `'binding'` as literal return type.

See #30235 for an example where this led to a false positive.

Pete Bacon Darwin 411524d341 feat(ivy): track compilation scope dependencies for components (#30238)
To support skipping analysis of a file containing a component
we need to know that none of the declarations that might affect
its ngtsc compilation have not changed. The files that we need to
check are those that contain classes from the `CompilationScope`
of the component. These classes are already tracked in the
`LocalModuleScopeRegistry`.

This commit modifies the `IvyCompilation` class to record the
files that are in each declared class's `CompilationScope` via
a new method, `recordNgModuleScopeDependencies()`, that is called
after all the handlers have been "resolved".

Further, if analysis is skipped for a declared class, then we need
to recover the analysis from the previous compilation run. To
support this, the `IncrementalState` class has been updated to
expose the `MetadataReader` and `MetadataRegistry` interfaces.
This is included in the `metaRegistry` object to capture these analyses,
and also in the `localMetaReader` as a fallback to use if the
current compilation analysis was skipped.

As part of incremental compilation performance improvements, we need
to track the dependencies of files due to expressions being evaluated by

The `PartialEvaluator` now accepts a `DependencyTracker` object, which is
used to track which files are visited when evaluating an expression.
The interpreter computes this `originatingFile` and stores it in the evaluation
`Context` so it can pass this to the `DependencyTracker.

The `IncrementalState` object implements this interface, which allows it to be
passed to the `PartialEvaluator` and so capture the file dependencies.

JoostK 638ba4a2cf fix(ivy): ngcc - prefer JavaScript source files when resolving module imports (#30017)
Packages that do not follow APF may have the declaration files in the same
directory as one source format, typically ES5. This is problematic for ngcc,
as it needs to create a TypeScript program with all JavaScript sources of
an entry-point, whereas TypeScript's module resolution mechanism would have
resolved an internal module import to the external facing .d.ts declaration
file, instead of the JavaScript source file. This behavior results in the
program to be analysed being incomplete.

This commit introduces a custom compiler host that recognizes the above
scenario and rewires the resolution of a .d.ts declaration file to its
JavaScript counterpart, if applicable.

Pete Bacon Darwin 4a2405929c refactor(ivy): ngcc - implement new module resolver (#29643)
When working out the dependencies between entry-points
ngcc must parse the import statements and then resolve the
import path to the actual file.  This is complicated because module
resolution is not trivial.

Previously ngcc used the node.js `require.resolve`, with some
hacking to resolve modules. This change refactors the `DependencyHost`
to use a new custom `ModuleResolver`, which is optimized for this use
case.

Moreover, because we are in full control of the resolution,
we can support TS `paths` aliases, where not all imports come from
`node_modules`. This is the case in some CLI projects where there are
compiled libraries that are stored locally in a `dist` folder.

ngtsc generates type constructors which infer the type of a directive based

the case of 'any' input values. For example, the inference of NgForOf fails

T[] = any

Alex Rickabaugh 3938563565 fix(ivy): don't reuse a ts.Program more than once in ngtsc (#30090)
ngtsc previously could attempt to reuse the main ts.Program twice. This
occurred when template type-checking was enabled and then an incremental
build was performed. This breaks a TypeScript invariant - ts.Programs can
only be reused once.

The creation of the template type-checking program reuses the main program,
rendering it moot. Then, on the next incremental build the main program
would be subject to reuse again, which would crash inside TypeScript.

This commit fixes the issue by reusing the template type-checking program
from the previous run on the next incremental build. Since under normal
circumstances the files in the type-checking program aren't changed, this
should be just as fast.

Testing strategy: a test is added in the incremental_spec which validates
that program reuse with type-checking turned on does not crash the compiler.

Alex Rickabaugh 8e73f9b0aa feat(compiler-cli): lower some exported expressions (#30038)
The compiler uses metadata to represent what it statically knows about
various expressions in a program. Occasionally, expressions in the program
for which metadata is extracted may contain sub-expressions which are not
representable in metadata. One such construct is an arrow function.

The compiler does not always need to understand such expressions completely.
For example, for a provider defined with `useValue`, the compiler does not
need to understand the value at all, only the outer provider definition. In
this case, the compiler employs a technique known as "expression lowering",
where it rewrites the provider expression into one that can be represented
in metadata. Chiefly, this involves extracting out the dynamic part (the
`useValue` expression) into an exported constant.

Lowering is applied through a heuristic, which considers the containing
statement as well as the field name of the expression.

Previously, this heuristic was not completely accurate in the case of
route definitions and the `loadChildren` field, which is lowered. If the
route definition using `loadChildren` existed inside a decorator invocation,
lowering was performed correctly. However, if it existed inside a standalone
variable declaration with an export keyword, the heuristic would conclude
that lowering was unnecessary. For ordinary providers this is true; however
the compiler attempts to fully understand the ROUTES token and thus even if
an array of routes is declared in an exported variable, any `loadChildren`
expressions within still need to be lowered.

This commit enables lowering of already exported variables under a limited
set of conditions (where the initializer expression is of a specific form).
This should enable the use of `loadChildren` in route definitions.

Alex Rickabaugh bea85ffe9c fix(ivy): match microsyntax template directives correctly (#29698)
Previously, Template.templateAttrs was introduced to capture attribute
bindings which originated from microsyntax (e.g. bindings in *ngFor="...").
This means that a Template node can have two different structures, depending
on whether it originated from microsyntax or from a literal <ng-template>.

In the literal case, the node behaves much like an Element node, it has
attributes, inputs, and outputs which determine which directives apply.
In the microsyntax case, though, only the templateAttrs should be used
to determine which directives apply.

Previously, both the t2_binder and the TemplateDefinitionBuilder were using
the wrong set of attributes to match directives - combining the attributes,
inputs, outputs, and templateAttrs of the Template node regardless of its
origin. In the TDB's case this wasn't a problem, since the TDB collects a
global Set of directives used in the template, so it didn't matter whether
the directive was also recognized on the <ng-template>. t2_binder's API
distinguishes between directives on specific nodes, though, so it's more
sensitive to mismatching.

In particular, this showed up as an assertion failure in template type-
checking in certain cases, when a directive was accidentally matched on
a microsyntax template element and also had a binding which referenced a
variable declared in the microsyntax. This resulted in the type-checker
attempting to generate a reference to a variable that didn't exist in that
scope.

The fix is to distinguish between the two cases and select the appropriate
set of attributes to match on accordingly.

Testing strategy: tested in the t2_binder tests.

Alex Rickabaugh 98f86de8da perf(ivy): template type-check the entire program in 1 file if possible (#29698)
The template type-checking engine previously would assemble a type-checking
program by inserting Type Check Blocks (TCBs) into existing user files. This
approach proved expensive, as TypeScript has to re-parse and re-type-check
those files when processing the type-checking program.

Instead, a far more performant approach is to augment the program with a
single type-checking file, into which all TCBs are generated. Additionally,
type constructors are also inlined into this file.

This is not always possible - both TCBs and type constructors can sometimes
require inlining into user code, particularly if bound generic type
parameters are present, so the approach taken is actually a hybrid. These
operations are inlined if necessary, but are otherwise generated in a single
file.

It is critically important that the original program also include an empty
version of the type-checking file, otherwise the shape of the two programs
will be different and TypeScript will throw away all the old program
information. This leads to a painfully slow type checking pass, on the same
order as the original program creation. A shim to generate this file in the
original program is therefore added.

Testing strategy: this commit is largely a refactor with no externally
observable behavioral differences, and thus no tests are needed.

Alex Rickabaugh f4c536ae36 feat(ivy): logical not and safe navigation operation handling in TCBs (#29698)
This commit adds support in the template type-checking engine for handling
the logical not operation and the safe navigation operation.

Safe navigation in particular is tricky, as the View Engine implementation
has a rather inconvenient flaw. View Engine checks a safe navigation
operation `a?.b` as:

```typescript
(a != null ? a!.b : null as any)
```

The type of this expression is always 'any', as the false branch of the
ternary has type 'any'. Thus, using null-safe navigation throws away the
type of the result, and breaks type-checking for the rest of the expression.

A flag is introduced in the type-checking configuration to allow Ivy to
mimic this behavior when needed.

Previously, metadata registration (the recording of collected metadata
during analysis of directives, pipes, and NgModules) was only used to

However, the template type-checker also needs information about registered

Filipe Silva 86a3f90954 fix(compiler-cli): pass config path to ts.parseJsonConfigFileContent (#29872)
The config path is an optional argument to `ts.parseJsonConfigFileContent`. When passed, it is added to the returned object as `options.configFilePath`, and `tsc` itself passes it in.

The new TS 3.4 [incremental](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-4.html) build functionality relies on this property being present: 025d826339/src/compiler/emitter.ts (L56-L57)

When using The compiler-cli `readConfiguration` the config path option isn't passed, preventing consumers (like @ngtools/webpack) from obtaining a complete config object.

This PR fixes this omission and should allow JIT users of @ngtools/webpack to set the `incremental` option in their tsconfig and have it be used by the TS program.

I tested this in JIT and saw a small decrease in build times in a small project. In AOT the incremental option didn't seem to be used at all, due to how `ngc` uses the TS APIs.

Olivier Combe 6a8cca7975 feat(ivy): use i18n locale data to determine the plural form of ICU expressions (#29249)
Plural ICU expressions depend on the locale (different languages have different plural forms). Until now the locale was hard coded as `en-US`.
For compatibility reasons, if you use ivy with AOT and bootstrap your app with `bootstrapModule` then the `LOCALE_ID` token will be set automatically for ivy, which is then used to get the correct plural form.
If you use JIT, you need to define the `LOCALE_ID` provider on the module that you bootstrap.
For `TestBed` you can use either `configureTestingModule` or `overrideProvider` to define that provider.
If you don't use the compat mode and start your app with `renderComponent` you need to call `ɵsetLocaleId` manually to define the `LOCALE_ID` before bootstrap. We expect this to change once we start adding the new i18n APIs, so don't rely on this function (there's a reason why it's a private export).

Kristiyan Kostadinov def73a6728 perf(ivy): avoid storing raw selectors in projectionDef (#29578)
Currently in Ivy we pass both the raw and parsed selectors to the projectionDef instruction, because the parsed selectors are used to match most nodes, whereas the raw ones are used to match against nodes with the ngProjectAs attribute. The raw selectors add a fair bit of code that won't be used in most cases, because ngProjectAs is somewhat rare.

These changes rework the compiler not to output the raw selectors in the projectionDef, but to parse the selector in ngProjectAs and to store it on the TAttributes. The logic for matching has also been changed so that it matches the pre-parsed ngProjectAs selector against the list of projection selectors.

tree-shaken for production builds.

This change moves the metadata for scope computations to a pure function
call that patches the scope references onto the module type. Because the
function is marked pure, it may be tree-shaken out during production builds
such that references to declarations and exports are dropped, which in turn
allows for tree-shaken any declaration that is not otherwise referenced.

JoostK 98f8b0f328 fix(ivy): ngcc - properly handle aliases class expressions (#29119)
In ES2015, classes could have been emitted as a variable declaration
initialized with a class expression. In certain situations, an intermediary
variable suffixed with `_1` is present such that the variable
declaration's initializer becomes a binary expression with its rhs being
the class expression, and its lhs being the identifier of the intermediate
variable. This structure was not recognized, resulting in such classes not
being considered as a class in `Esm2015ReflectionHost`.

As a consequence, the analysis of functions/methods that return a
`ModuleWithProviders` object did not take the methods of such classes into
account.

Another edge-case with such intermediate variable was that static
properties would not be considered as class members. A testcase was added
to prevent regressions.

This commit introduces a mechanism for incremental compilation to the ngtsc
compiler.

Previously, incremental information was used in the construction of the
ts.Program for subsequent compilations, but was not used in ngtsc itself.

This commit adds an IncrementalState class, which tracks state between ngtsc
compilations. Currently, this supports skipping the TypeScript emit step
when the compiler can prove the contents of emit have not changed.

This is implemented for @Injectables as well as for files which don't
contain any Angular decorated types. These are the only files which can be
proven to be safe today.

Alex Rickabaugh 3e569767e3 fix(ivy): avoid remote scoping if it's not actually required (#29404)
Currently, ngtsc decides to use remote scoping if the compilation of a
component may create a cyclic import. This happens if there are two
components in a scope (say, A and B) and A directly uses B. During
compilation of B ngtsc will then note that if B were to use A, a cycle would
be generated, and so it will opt to use remote scoping for B.

ngtsc already uses the R3TargetBinder to correctly track the imports that
are actually required, for future cycle tracking. This commit expands that
usage to not trigger remote scoping unless B actually does consume A in its
template.

George Kalpakas bb6a3632f6 refactor(ivy): correctly type class declarations in `ngtsc`/`ngcc` (#29209)
Previously, several `ngtsc` and `ngcc` APIs dealing with class
declaration nodes used inconsistent types. For example, some methods of
the `DecoratorHandler` interface expected a `ts.Declaration` argument,
but actual `DecoratorHandler` implementations specified a stricter
`ts.ClassDeclaration` type.

As a result, the stricter methods would operate under the incorrect
assumption that their arguments were of type `ts.ClassDeclaration`,
while the actual arguments might be of different types (e.g. `ngcc`
would call them with `ts.FunctionDeclaration` or
`ts.VariableDeclaration` arguments, when compiling ES5 code).

Additionally, since we need those class declarations to be referenced in
other parts of the program, `ngtsc`/`ngcc` had to either repeatedly
check for `ts.isIdentifier(node.name)` or assume there was a `name`
identifier and use `node.name!`. While this assumption happens to be
true in the current implementation, working around type-checking is
error-prone (e.g. the assumption might stop being true in the future).

This commit fixes this by introducing a new type to be used for such
class declarations (`ts.Declaration & {name: ts.Identifier}`) and using
it consistently throughput the code.

Pete Bacon Darwin bdcbd9ed4b fix(ivy): ngcc - teach Esm5ReflectionHost about aliased variables (#29092)
Sometimes, in ESM5 code, aliases to exported variables are used internally
to refer to the exported value. This prevented some analysis from being
able to match up a reference to an export to the actual export itself.

For example in the following code:

```
var HttpClientXsrfModule = /** @class */ (function () {
  function HttpClientXsrfModule() {
  }
  HttpClientXsrfModule_1 = HttpClientXsrfModule;
  HttpClientXsrfModule.withOptions = function (options) {
      if (options === void 0) { options = {}; }
      return {
          ngModule: HttpClientXsrfModule_1,
          providers: [],
      };
  };
  var HttpClientXsrfModule_1;
  HttpClientXsrfModule = HttpClientXsrfModule_1 = tslib_1.__decorate([
      NgModule({
          providers: [],
      })
  ], HttpClientXsrfModule);
  return HttpClientXsrfModule;
}());
```

We were not able to tell that the `ngModule: HttpClientXsrfModule_1` property
assignment was actually meant to refer to the `function HttpClientXrsfModule()`
declaration.  This caused the `ModuleWithProviders` processing to fail.

This commit ensures that we can compile typings files using the ESM5
format, so we can now update the examples boilerplate tool so that it
does not need to compile the ESM2015 format at all.

BREAKING CHANGE:

The `proertiesToConsider` option replaces the previous `formats` option,
which specified the final bundle format, rather than the property in the

If you were using this option to compile only specific bundle formats,
you must now modify your usage to pass in the properties in the package.json
that map to the format that you wish to compile.

Alex Rickabaugh ae4a86e3b5 fix(ivy): don't track identifiers of ffr-resolved references (#29387)
This fix is for a bug in the ngtsc PartialEvaluator, which statically
evaluates expressions.

Sometimes, evaluating a reference requires resolving a function which is
declared in another module, and thus no function body is available. To
support this case, the PartialEvaluator has the concept of a foreign
function resolver.

This allows the interpretation of expressions like:

const router = RouterModule.forRoot([]);

even though the definition of the 'forRoot' function has no body. In
ngtsc today, this will be resolved to a Reference to RouterModule itself,
via the ModuleWithProviders foreign function resolver.

However, the PartialEvaluator also associates any Identifiers in the path
of this resolution with the Reference. This is done so that if the user
writes

const x = imported.y;

'x' can be generated as a local identifier instead of adding an import for
'y'.

This was at the heart of a bug. In the above case with 'router', the
PartialEvaluator added the identifier 'router' to the Reference generated
(through FFR) to RouterModule.

This is not correct. References that result from FFR expressions may not
have the same value at runtime as they do at compile time (indeed, this is
not the case for ModuleWithProviders). The Reference generated via FFR is
"synthetic" in the sense that it's constructed based on a useful
interpretation of the code, not an accurate representation of the runtime
value. Therefore, it may not be legal to refer to the Reference via the
'router' identifier.

This commit adds the ability to mark such a Reference as 'synthetic', which
allows the PartialEvaluator to not add the 'router' identifier down the
line. Tests are included for both the PartialEvaluator itself as well as the
resultant buggy behavior in ngtsc overall.

Paul Gschwendtner 105cfaf5e4 fix(compiler-cli): incorrect metadata bundle for multiple unnamed re-exports (#29360)
Currently if an Angular library has multiple unnamed module re-exports, NGC will
generate incorrect metdata if the project is using the flat-module bundle option.

e.g.

_public-api.ts_
```ts
export * from '@mypkg/secondary1';
export * from '@mypkg/secondary2';
```

There are clearly two unnamed re-exports in the `public-api.ts` file. NGC right now
accidentally overwrites all previous re-exports with the last one. Resulting in the
generated metadata only containing a reference to `@mypkg/secondary2`.

This is problematic as it is common for primary library entry-points to have
multiple re-exports (e.g. Material re-exporting all public symbols; or flex-layout
exporting all public symbols from their secondary entry-points).

Currently Angular Material works around this issue by manually creating
a metadata file that declares the re-exports from all unnamed re-exports.

(see: https://github.com/angular/material2/blob/master/tools/package-tools/build-release.ts#L78-L85)

This workaround works fine currently, but is no longer easily integrated when
building the package output with Bazel. In order to be able to build such
libraries with Bazel (Material/flex-layout), we need to make sure that NGC
generates the proper flat-module metadata bundle.

However, when generating the resulting ngModuleDef, the forward nature of

Alex Rickabaugh ccb70e1c64 fix(ivy): reuse default imports in type-to-value references (#29266)
This fixes an issue with commit b6f6b117. In this commit, default imports
processed in a type-to-value conversion were recorded as non-local imports
with a '*' name, and the ImportManager generated a new default import for
them. When transpiled to ES2015 modules, this resulted in the following
correct code:

import i3 from './module';

// somewhere in the file, a value reference of i3:
{type: i3}

However, when the AST with this synthetic import and reference was
transpiled to non-ES2015 modules (for example, to commonjs) an issue
appeared:

var module_1 = require('./module');
{type: i3}

TypeScript renames the imported identifier from i3 to module_1, but doesn't
substitute later references to i3. This is because the import and reference
are both synthetic, and never went through the TypeScript AST step of
"binding" which associates the reference to its import. This association is
important during emit when the identifiers might change.

Synthetic (transformer-added) imports will never be bound properly. The only
possible solution is to reuse the user's original import and the identifier
from it, which will be properly downleveled. The issue with this approach
(which prompted the fix in b6f6b117) is that if the import is only used in a
type position, TypeScript will mark it for deletion in the generated JS,
even though additional non-type usages are added in the transformer. This
again would leave a dangling import.

To work around this, it's necessary for the compiler to keep track of
identifiers that it emits which came from default imports, and tell TS not
to remove those imports during transpilation. A `DefaultImportTracker` class
is implemented to perform this tracking. It implements a
`DefaultImportRecorder` interface, which is used to record two significant
pieces of information:

* when a WrappedNodeExpr is generated which refers to a default imported
  value, the ts.Identifier is associated to the ts.ImportDeclaration via
  the recorder.
* when that WrappedNodeExpr is later emitted as part of the statement /
  expression translators, the fact that the ts.Identifier was used is
  also recorded.

Combined, this tracking gives the `DefaultImportTracker` enough information
to implement another TS transformer, which can recognize default imports
which were used in the output of the Ivy transform and can prevent them
from being elided. This is done by creating a new ts.ImportDeclaration for
the imports with the same ts.ImportClause. A test verifies that this works.

Alan Agius a5b8420234 fix(ivy): render alias exports for private declarations if possible (#28735)
Sometimes declarations are not exported publicly but are exported under
a private name. In this case, rather than adding a completely new
export to the entry point, we should create an export that aliases the
private name back to the original public name.

This is important when the typings files have been rolled-up using a tool
such as the [API Extractor](https://api-extractor.com/). In this case
the internal type of an aliased private export will be removed completely
from the typings file, so there is no "original" type to re-export.

For example:

If there are the following TS files:

**entry-point.ts**

```ts
export {Internal as External} from './internal';
```

**internal.ts**

```ts
export class Internal {
  foo(): void;
}
```

Then the API Extractor might roll up the .d.ts files into:

```ts
export declare class External {
  foo(): void;
}
```

In this case ngcc should add an export so the file looks like:

```ts
export declare class External {
  foo(): void;
}
export {External as Internal};
```

Alex Rickabaugh c37ec8b255 fix(ivy): produce ts.Diagnostics for NgModule scope errors (#29191)
Previously, when the NgModule scope resolver discovered semantic errors
within a users NgModules, it would throw assertion errors. TODOs in the
codebase indicated these should become ts.Diagnostics eventually.

Besides producing better-looking errors, there is another reason to make
this change asap: these assertions were shadowing actual errors, via an
interesting mechanism:

1) a component would produce a ts.Diagnostic during its analyze() step
2) as a result, it wouldn't register component metadata with the scope
   resolver
3) the NgModule for the component references it in exports, which was
   detected as an invalid export (no metadata registering it as a
   component).
4) the resulting assertion error would crash the compiler, hiding the
   real cause of the problem (an invalid component).

This commit should mitigate this problem by converting scoping errors to
proper ts.Diagnostics. Additionally, we should consider registering some
marker indicating a class is a directive/component/pipe without actually
requiring full metadata to be produced for it, which would allow suppression
of errors like "invalid export" for such invalid types.

In the TypeScript compiler API, emit() can be performed either on a single
ts.SourceFile or on the entire ts.Program simultaneously.

ngtsc previously used whole-program emit, which was convenient to use while
spinning up the project but has a significant drawback: it causes a type
checking operation to occur for the whole program, including .d.ts files.
In large Bazel environments (such as Google's codebase), an ngtsc invocation
can have a few .ts files and thousands of .d.ts inputs. This unwanted type
checking is therefore a significant drain on performance.

Pete Bacon Darwin f535f31d78 fix(ivy): match attribute selectors for content projection with inline-templates (#29041)
The content projection mechanism is static, in that it only looks at the static
template nodes before directives are matched and change detection is run.
When you have a selector-based content projection the selection is based
on nodes that are available in the template.

For example:

```
<ng-content selector="[some-attr]"></ng-content>
```

would match

```
<div some-attr="..."></div>
```

If you have an inline-template in your projected nodes. For example:

```
<div *ngIf="..." some-attr="..."></div>
```

This gets pre-parsed and converted to a canonical form.

For example:

```
<ng-template [ngIf]="...">
  <div some-attr=".."></div>
</ng-template>
```

Note that only structural attributes (e.g. `*ngIf`) stay with the `<ng-template>`
node. The other attributes move to the contained element inside the template.

When this happens in ivy, the ng-template content is removed
from the component template function and is compiled into its own
template function. But this means that the information about the
attributes that were on the content are lost and the projection
selection mechanism is unable to match the original
`<div *ngIf="..." some-attr>`.

This commit adds support for this in ivy. Attributes are separated into three
groups (Bindings, Templates and "other"). For inline-templates the Bindings
and "other" types are hoisted back from the contained node to the `template()`
instruction, so that they can be used in content projection matching.

Alex Rickabaugh 881807dc36 fix(ivy): never use imported type references as values (#29111)
ngtsc occasionally converts a type reference (such as the type of a
parameter in a constructor) to a value reference (argument to a
directiveInject call). TypeScript has a bad habit of sometimes removing
the import statement associated with this type reference, because it's a
type only import when it initially looks at the file.

A solution to this is to always add an import to refer to a type position
value that's imported, and not rely on the existing import.

Alex Rickabaugh 3e5c1bcb9f fix(ivy): track cyclic imports that are added (#29040)
ngtsc has cyclic import detection, to determine when adding an import to a
directive or pipe would create a cycle. However, this detection must also
account for already inserted imports, as it's possible for both directions
of a circular import to be inserted by Ivy (as opposed to at least one of
those edges existing in the user's program).

This commit fixes the circular import detection for components to take into
consideration already added edges. This is difficult for one critical
reason: only edges to files which will *actually* be imported should be
considered. However, that depends on which directives & pipes are used in
a given template, which is currently only known by running the
TemplateDefinitionBuilder during the 'compile' phase. This is too late; the
decision whether to use remote scoping (which consults the import graph) is
made during the 'resolve' phase, before any compilation has taken place.

Thus, the only way to correctly consider synthetic edges is for the compiler
to know exactly which directives & pipes are used in a template during
'resolve'. There are two ways to achieve this:

1) refactor `TemplateDefinitionBuilder` to do its work in two phases, with
directive matching occurring as a separate step which can be performed
earlier.

2) use the `R3TargetBinder` in the 'resolve' phase to independently bind the
template and get information about used directives.

Option 1 is ideal, but option 2 is currently used for practical reasons. The
cost of binding the template can be shared with template-typechecking.

Alex Rickabaugh b50283ed67 fix(ivy): support dynamic host attribute bindings (#29033)
In the @Component decorator, the 'host' field is an object which represents
host bindings. The type of this field is complex, but is generally of the
form {[key: string]: string}. Several different kinds of bindings can be
specified, depending on the structure of the key.

For example:

```
@Component({
  host: {'[prop]': 'someExpr'}
})
```

will bind an expression 'someExpr' to the property 'prop'. This is known to
be a property binding because of the square brackets in the binding key.

If the binding key is a plain string (no brackets or parentheses), then it
is known as an attribute binding. In this case, the right-hand side is not
interpreted as an expression, but is instead a constant string.

There is no actual requirement that at build time, these constant strings
are known to the compiler, but this was previously enforced as a side effect
of requiring the binding expressions for property and event bindings to be
statically known (as they need to be parsed). This commit breaks that
relationship and allows the attribute bindings to be dynamic. In the case
that they are dynamic, the references to the dynamic values are reflected
into the Ivy instructions for attribute bindings.

Alex Rickabaugh a23a0bc3a4 feat(ivy): support tracking the provenance of DynamicValue (#29033)
DynamicValues are generated whenever a partially evaluated expression is
unable to be resolved statically. They contain a reference to the ts.Node
which wasn't resolvable.

They can also be nested. For example, the expression 'a + b' is resolvable
only if 'a' and 'b' are themselves resolvable. If either 'a' or 'b' resolve
to a DynamicValue, the whole expression must also resolve to a DynamicValue.

Previously, if 'a' resolved to a DynamicValue, the entire expression might
have been resolved to the same DynamicValue. This correctly indicated that
the expression wasn't resolvable, but didn't return a reference to the
shallow node that couldn't be resolved (the expression 'a + b'), only a
reference to the deep node that couldn't be resolved ('a').

In certain situations, it's very useful to know the shallow unresolvable
node (for example, to use it verbatim in the output). To support this,
the partial evaluator is updated to always wrap DynamicValue to point to
each unresolvable expression as it's processed, ensuring the receiver can
determine exactly which expression node failed to resolve.

Alex Rickabaugh c1392ce618 feat(ivy): produce and consume ES2015 re-exports for NgModule re-exports (#28852)
In certain configurations (such as the g3 repository) which have lots of
small compilation units as well as strict dependency checking on generated
code, ngtsc's default strategy of directly importing directives/pipes into
components will not work. To handle these cases, an additional mode is
introduced, and is enabled when using the FileToModuleHost provided by such
compilation environments.

In this mode, when ngtsc encounters an NgModule which re-exports another
from a different file, it will re-export all the directives it contains at
the ES2015 level. The exports will have a predictable name based on the
FileToModuleHost. For example, if the host says that a directive Foo is
from the 'root/external/foo' module, ngtsc will add:

```
export {Foo as ɵng$root$external$foo$$Foo} from 'root/external/foo';
```

Consumers of the re-exported directive will then import it via this path
instead of directly from root/external/foo, preserving strict dependency
semantics.

Paul Gschwendtner 58436fd81a fix(ivy): unable to import shim factory files on case-insensitive platforms (#28831)
This change is kind of similar to #27466, but instead of ensuring that
these shims can be generated, we also need to make sure that developers
are able to also use the factory shims like with `ngc`.

This issue is now surfacing because we have various old examples which
are now also built with `ngtsc`  (due to the bazel migration). On case insensitive
platforms (e.g. windows) these examples cannot be built because ngtsc fails
the app imports a generated shim file (such as the factory shim files).

This is because the `GeneratedShimsHostWrapper` TypeScript host uses
the `getCanonicalFileName` method in order to check whether a given
file/module exists in the generator file maps. e.g.

```
// Generator Map:
'C:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ngfactory.ts' =>
'C:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ts',

// Path passed into `fileExists`
C:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ngfactory.ts

// After getCanonicalFileName (notice the **lower-case drive name**)
c:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ngfactory.ts
```

As seen above, the generator map does not use the canonical file names, as well as
TypeScript internally does not pass around canonical file names. We can fix this by removing
the manual call to `getCanonicalFileName` and just following TypeScript internal-semantics.

Paul Gschwendtner 4131715df5 fix(compiler-cli): incorrect bundled metadata for static class member call expressions (#28762)
Currently if developers use call expressions in their static
class members ([like we do in Angular](https://github.com/angular/angular/blob/master/packages/core/src/change_detection/differs/keyvalue_differs.ts#L121)),
the metadata that is generated for flat modules is invalid. This
is because the metadata bundler logic currently does not handle
call expressions in static class members and the symbol references
are not rewritten to avoid relative paths in the bundle.

Static class members using a call expression are not relevant for
the ViewEngine AOT compilation, but it is problematic that the
bundled metadata references modules using their original relative
path. This means that the bundled metadata is no longer encapsulated
and depends on other emitted files to be emitted in the proper place.

These incorrect relative paths can now cause issues where NGC
looks for the referenced symbols in the incorrect path. e.g.

```
src/
 | lib/
    | index.ts -> References the call expression using `../../di`
```

Now the metadata looks like that:

```
node_modules/
  | @angular/
  -- | core/
  -- -- | core.metadata.json -> Says that the call expr. is in `../../di`.
  | di/
```

Now if NGC tries to use the metadata files and create the summary files,
NGC resolves the call expression to the `node_modules/di` module. Since
the "unexpected" module does not contain the desired symbol, NGC will
error out.

We should fix this by ensuring that we don't ship corrupted metadata
to NPM which contains relative references that can cause such
failures (other imports can be affected as well; it depends on what
modules the developer has installed and how we import our call
expressions).

Kristiyan Kostadinov 80a5934af6 fix(ivy): support schemas at runtime (#28637)
Accounts for schemas in when validating properties in Ivy.

This PR resolves FW-819.

A couple of notes:
* I had to rework the test slightly, in order to have it fail when we expect it to. The one in master is passing since Ivy's validation runs during the update phase, rather than creation.
* I had to deviate from the design in FW-819 and not add an `enableSchema` instruction, because the schema is part of the `NgModule` scope, however the scope is only assigned to a component once all of the module's declarations have been resolved and some of them can be async. Instead, I opted to have the `schemas` on the component definition.

Alex Rickabaugh 423b39e216 feat(ivy): use fileNameToModuleName to emit imports when it's available (#28523)
The ultimate goal of this commit is to make use of fileNameToModuleName to
get the module specifier to use when generating an import, when that API is
available in the CompilerHost that ngtsc is created with.

As part of getting there, the way in which ngtsc tracks references and
generates import module specifiers is refactored considerably. References
are tracked with the Reference class, and previously ngtsc had several
different kinds of Reference. An AbsoluteReference represented a declaration
which needed to be imported via an absolute module specifier tracked in the
AbsoluteReference, and a RelativeReference represented a declaration from
the local program, imported via relative path or referred to directly by
identifier if possible. Thus, how to refer to a particular declaration was
encoded into the Reference type _at the time of creation of the Reference_.

This commit refactors that logic and reduces Reference to a single class
with no subclasses. A Reference represents a node being referenced, plus
context about how the node was located. This context includes a
"bestGuessOwningModule", the compiler's best guess at which absolute
module specifier has defined this reference. For example, if the compiler
arrives at the declaration of CommonModule via an import to @angular/common,
then any references obtained from CommonModule (e.g. NgIf) will also be
considered to be owned by @angular/common.

A ReferenceEmitter class and accompanying ReferenceEmitStrategy interface
are introduced. To produce an Expression referring to a given Reference'd
node, the ReferenceEmitter consults a sequence of ReferenceEmitStrategy
implementations.

Several different strategies are defined:

- LocalIdentifierStrategy: use local ts.Identifiers if available.
- AbsoluteModuleStrategy: if the Reference has a bestGuessOwningModule,
  import the node via an absolute import from that module specifier.
- LogicalProjectStrategy: if the Reference is in the logical project
  (is under the project rootDirs), import the node via a relative import.
- FileToModuleStrategy: use a FileToModuleHost to generate the module
  specifier by which to import the node.

Depending on the availability of fileNameToModuleName in the CompilerHost,
then, a different collection of these strategies is used for compilation.

Alex Rickabaugh 99d8582882 feat(ivy): support @Injectable on already decorated classes (#28523)
Previously, ngtsc would throw an error if two decorators were matched on
the same class simultaneously. However, @Injectable is a special case, and
it appears frequently on component, directive, and pipe classes. For pipes
in particular, it's a common pattern to treat the pipe class also as an
injectable service.

ngtsc actually lacked the capability to compile multiple matching
decorators on a class, so this commit adds support for that. Decorator
handlers (and thus the decorators they match) are classified into three
categories: PRIMARY, SHARED, and WEAK.

PRIMARY handlers compile decorators that cannot coexist with other primary
decorators. The handlers for Component, Directive, Pipe, and NgModule are
marked as PRIMARY. A class may only have one decorator from this group.

SHARED handlers compile decorators that can coexist with others. Injectable
is the only decorator in this category, meaning it's valid to put an
@Injectable decorator on a previously decorated class.

WEAK handlers behave like SHARED, but are dropped if any non-WEAK handler
matches a class. The handler which compiles ngBaseDef is WEAK, since
ngBaseDef is only needed if a class doesn't otherwise have a decorator.

Tests are added to validate that @Injectable can coexist with the other
decorators and that an error is generated when mixing the primaries.

Alex Rickabaugh d2742cf473 feat(ivy): compile @Injectable on classes not meant for DI (#28523)
In the past, @Injectable had no side effects and existing Angular code is
therefore littered with @Injectable usage on classes which are not intended
to be injected.

A common example is:

@Injectable()
class Foo {
  constructor(private notInjectable: string) {}
}

and somewhere else:

providers: [{provide: Foo, useFactory: ...})

Here, there is no need for Foo to be injectable - indeed, it's impossible
for the DI system to create an instance of it, as it has a non-injectable
constructor. The provider configures a factory for the DI system to be
able to create instances of Foo.

Adding @Injectable in Ivy signifies that the class's own constructor, and
not a provider, determines how the class will be created.

This commit adds logic to compile classes which are marked with @Injectable
but are otherwise not injectable, and create an ngInjectableDef field with
a factory function that throws an error. This way, existing code in the wild
continues to compile, but if someone attempts to use the injectable it will
fail with a useful error message.

In the case where strictInjectionParameters is set to true, a compile-time
error is thrown instead of the runtime error, as ngtsc has enough
information to determine when injection couldn't possibly be valid.

Paul Gschwendtner 91b7152852 feat(compiler-cli): no longer re-export external symbols by default (#28633)
With #28594 we refactored the `@angular/compiler` slightly to
allow opting out from external symbol re-exports which are
enabled by default.

Since symbol re-exports only benefit projects which have a
very strict dependency enforcement, external symbols should
not be re-exported by default as this could grow the size of
factory files and cause unexpected behavior with Angular's
AOT symbol resolving (e.g. see: #25644).

Note that the common strict dependency enforcement for source
files does still work with external symbol re-exports disabled,
but there are also strict dependency checks that enforce strict
module dependencies also for _generated files_ (such as the
ngfactory files). This is how Google3 manages it's dependencies
and therefore external symbol re-exports need to be enabled within
Google3.

Also "ngtsc" also does not provide any way of using external symbol
re-exports, so this means that with this change, NGC can partially
match the behavior of "ngtsc" then (unless explicitly opted-out).

As mentioned before, internally at Google symbol re-exports need to
be still enabled, so the `ng_module` Bazel rule will enable the symbol
re-exports by default when running within Blaze.

Fixes #25644.

JoostK 2afc40608d fix(ivy): support injecting ChangeDetectorRef on templates (#27565)
Previously, using a pipe in an input binding on an ng-template would
evaluate the pipe in the context of node that was processed before the
template. This caused the retrieval of e.g. ChangeDetectorRef to be
incorrect, resulting in one of the following bugs depending on the
template's structure:

1. If the template was at the root of a view, the previously processed
node would be the component's host node outside of the current view.
Accessing that node in the context of the current view results in a crash.
2. For templates not at the root, the ChangeDetectorRef injected into the
pipe would correspond with the previously processed node. If that node
hosts a component, the ChangeDetectorRef would not correspond with the
view that the ng-template is part of.

The solution to the above problem is two-fold:

1. Template compilation is adjusted such that the template instruction
is emitted before any instructions produced by input bindings, such as
pipes. This ensures that pipes are evaluated in the context of the
template's container node.
2. A ChangeDetectorRef can be requested for container nodes.

Pete Bacon Darwin 08de52b9f0 feat(ivy): add source mappings to compiled Angular templates (#28055)
During analysis, the `ComponentDecoratorHandler` passes the component
template to the `parseTemplate()` function. Previously, there was little or
no information about the original source file, where the template is found,
passed when calling this function.

Now, we correctly compute the URL of the source of the template, both
for external `templateUrl` and in-line `template` cases. Further in the
in-line template case we compute the character range of the template
in its containing source file; *but only in the case that the template is
a simple string literal*. If the template is actually a dynamic value like
an interpolated string or a function call, then we do not try to add the
originating source file information.

The translator that converts Ivy AST nodes to TypeScript now adds these
template specific source mappings, which account for the file where
the template was found, to the templates to support stepping through the
template creation and update code when debugging an Angular application.

Note that some versions of TypeScript have a bug which means they cannot
support external template source-maps. We check for this via the
`canSourceMapExternalTemplates()` helper function and avoid trying to
add template mappings to external templates if not supported.

Andrew Kushnir bb94434d85 fix(ivy): Content Queries inheritance fix (#28324)
Prior to this change contentQueriesRefresh functions that represent refresh logic for @ContentQuery list were not composable, which caused problems in case one Directive inherits another one and both of them contain Content Queries. Due to the fact that we used indices to reference queries in refresh function, results were placed into wrong Queries. In order to avoid that we no longer use indices to reference queries and instead maintain current content query index while iterating through them. This allows us to compose contentQueriesRefresh functions and make inheritance feature work with Content Queries.

Kristiyan Kostadinov ebac5dba38 fix(ivy): don't generate code for blank NgModule fields (#28387)
Currently `compileNgModule` generates an empty array for optional fields that are omitted from an `NgModule` declaration (e.g. `bootstrap`, `exports`). This isn't necessary, because `defineNgModule` has some code to default these fields to empty arrays at runtime if they aren't defined. The following changes will only output code if there are values for the particular field.
