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.

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

Before this change we would systematically call LQueries.clone() when executting

LQueries can be mutated under 2 conditions only:
- we are crossing an element that has directives with content queries
(new queries must be added);
- we are descending into element hierarchy (creating a child element of an existing element)
and the current LQueries object is tracking shallow queries (shallow queries are removed).
With this PR LQueires.clone() is only done when needed and this gratelly reduces number

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).

fix(@schematics/angular): TypeScript related migrations should cater for BOM
In the CLI `UpdateRecorder` methods such as `insertLeft`, `remove` etc.. accepts positions which are not offset by a BOM. This is because when a file has a BOM a different recorder will be used https://github.com/angular/angular-cli/blob/master/packages/angular_devkit/schematics/src/tree/recorder.ts#L72 which caters for an addition offset/delta.
The main reason for this is that when a developer is writing a schematic they shouldn't need to compute the offset based if a file has a BOM or not and is handled out of the box.
Example
```ts
recorder.insertLeft(5, 'true');
```
However this is unfortunate in the case if a ts SourceFile is used and one uses `getWidth` and `getStart` method they will already be offset by 1, which at the end it results in a double offset and hence the problem.

Two issues with DebugNode/DebugElement in Ivy were causing problems in user
tests.
1. The DebugNodes returned by Ivy were not actually instances of DebugNode.
This was due to an issue with the Ivy switch logic in debug_node.ts.
The declaration of the exported DebugNode reference was set to
`DebugNode__PRE_R3__ as any`. The cast prevented the Ivy switch transform
from detecting this as a switchable declaration. The transform cannot handle
arbitrary syntax, and exports *must* be of the form "const x = y__PRE_R3__;"
or they will not work. The cast to any in this case was not needed, so this
commit removes it.
2. DebugNodes returned by Ivy multiple times for the same element were not
reference-identical. This was previously considered a minor breaking change
in Ivy, but testing has shown that users depend on referential equality of
DebugNodes. This commit caches a DebugNode on a DOM node when first creating
it, to allow returning the same instance in subsequent operations.

The R3TargetBinder "binds" an Angular template AST, computing semantic

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

which desugars to:
<ng-template ngIf [ngIf]="foo" let-foo="ngIf">

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`,

maps to that variable.

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).

This is a new feature of the Ivy TestBed.
A common user pattern is to test one component with another. This is
commonly done by creating a `TestFixture` component which exercises the
main component under test.
This pattern is more difficult if the component under test is declared in an
NgModule but not exported. In this case, overriding the module is necessary.
In g3 (and View Engine), it's possible to use an NgSummary to override the
recompilation of a component, and depend on its AOT compiled factory. The
way this is implemented, however, specifying a summary for a module
effectively overrides much of the TestBed's other behavior. For example, the
following is legal:
```typescript
TestBed.configureTestingModule({
declarations: [FooCmp, TestFixture],
imports: [FooModule],
aotSummaries: [FooModuleNgSummary],
});
```
Here, `FooCmp` is declared in both the testing module and in the imported
`FooModule`. However, because the summary is provided, `FooCmp` is not
compiled within the context of the testing module, but _is_ made available
for `TestFixture` to use, even if it wasn't originally exported from
`FooModule`.
This pattern breaks in Ivy - because summaries are a no-op, this amounts
to a true double declaration of `FooCmp` which raises an error.
Fixing this in user code is possible, but is difficult to do in an
automated or backwards compatible way. An alternative solution is
implemented in this PR.
This PR attempts to capture the user intent of the following previously
unsupported configuration:
```typescript
TestBed.configureTestingModule({
declarations: [FooCmp, TestFixture],
imports: [FooModule],
});
```
Note that this is the same as the configuration above in Ivy, as the
`aotSummaries` value provided has no effect.
The user intent here is interpreted as follows:
1) `FooCmp` is a pre-existing component that's being used in the test
(via import of `FooModule`). It may or may not be exported by this
module.
2) `FooCmp` should be part of the testing module's scope. That is, it
should be visible to `TestFixture`. This is because it's listed in
`declarations`.
This feature effectively makes the `TestBed` testing module special. It's
able to declare components without compiling them, if they're already
compiled (or configured to be compiled) in the imports. And crucially, the
behavior matches the first example with the summary, making Ivy backwards
compatible with View Engine for tests that use summaries.

With Ivy, injecting a `ViewContainerRef` for a `<ng-container>` element
results in two comments generated in the DOM. One comment as host
element for the `ElementContainer` and one for the generated `LContainer`

This is problematic as developers expect the same anchor element for
the `LContainer` and the `ElementContainer` in order to be able to move
the host element of `<ng-container>` without leaving the actual
`LContainer` anchor element at the original location.
This worked differently in View Engine and various applications might
depend on the behavior where the `ViewContainerRef` shares the anchor
comment node with the host comment node of the `<ng-container>`. For
example `CdkTable` from `@angular/cdk` moves around the host element of
a `<ng-container>` and also expects embedded views to be inserted next
to the moved `<ng-container>` host element.

In PR #19558, we fixed a bug in `TestBed.overrideProvider` where

it turned out that since this bug had been around for quite a bit,
many apps were relying on the broken behavior where the providers

introduced to mimic the old behavior so that apps would have a
longer time period to migrate their code.
2 years and 3 versions later, it is time to remove the temporary
method. This commit removes `TestBed.deprecatedOverrideProvider`
altogether. Any usages of `TestBed.deprecatedOverrideProvider`
should be replaced with `TestBed.overrideProvider`. This may mean
that providers that were not created before will now be instantiated,
which could mean that your tests need to provide more mocks or stubs

<div *ngFor="let user of users | slice:0:2">{{ user.typo }}</div>
|
`typo` does not exist on type `UserModel`
whereas it is currently not catched (as the return of `slice` is `any`) neither in VE nor in Ivy.
BREAKING CHANGE
`SlicePipe` now only accepts an array of values, a string, null or undefined.
This was already the case in practice, and it still throws at runtime if another type is given.
But it is now a compilation error to try to call it with an unsupported type.

Previously we defensively wrapped expressions in case they ran afoul of
precedence rules. For example, it would be easy to create the TS AST structure
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.
This commit removes these defensive paraenthesis in the cases of binary
and ternary operations.

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.

This is the first refactor PR designed to change how styling bindings
(i.e. `[style]` and `[class]`) behave in Ivy. Instead of having a heavy
element-by-element context be generated for each element, this new
refactor aims to use a single context for each `tNode` element that is
examined and iterated over when styling values are to be applied to the
element.
This patch brings this new functionality to prop-based bindings such as
`[style.prop]` and `[class.name]`.

Previously, in order to assert that the promise was not resolved, an
error was thrown when the promise was resolved successfully. At the
same, `.catch()` was used to silence the (expected) promise rejection.
However, the chained `.catch()` handler would also catch (and swallow)
the error thrown on resolving the promise, making the test pass, even if
the promise was not rejected.
This commit fixes it by ensuring that the error thrown on resolving the
promise is not caught by the rejection handler.

Previously, [this test][1] would occasionally fail (e.g. on CI) with
"Template cache was not found in $templateCache". This was due to a
combination of:
1. [That test][2] (which removes the cache) being run right before the
failing test.
2. The async `TestBed.compileComponents()` operation run in the
`beforeEach()` block (which sets the cache) not having completed
before the `it()` block.
This commit fixes the issue by ensuring the cache is always set, before
instantiating `CachedResourceLoader`.
This commit also moves some operations that are only needed in one test
from the `beforeEach()` block to that test's `it()` block.

Previously the same `Renderer` was used to render typings (.d.ts)
files. But the new `UmdRenderer` is not able to render typings files
correctly.
This commit splits out the typings rendering from the src rendering.
To achieve this the previous renderers have been refactored from
sub-classes of the abstract `Renderer` class to classes that implement
the `RenderingFormatter` interface, which are then passed to the
`Renderer` and `DtsRenderer` to modify its rendering behaviour.
Along the way a few utility interfaces and classes have been moved
around and renamed for clarity.

Previously, ngtsc would fail to evaluate expressions that access properties
from e.g. the `window` object. This resulted in hard to debug error messages

evaluating such expressions no longer fail but instead result in a `DynamicValue`.

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.

In View Engine, we would simply ignore host style bindings on template nodes. In Ivy,
we are throwing a "Cannot read length of undefined" error instead. For backwards
compatibility, we should also ignore these bindings rather than blowing up.

In View engine it is possible to instantiate a service that that has no
`@Injectable` decorator as long as it satisfies one of:
1) It has no dependencies and so a constructor with no parameters.
This is already supported in Ivy.
2) It has no constructor of its own and sub-classes a service which has
dependencies but has its own `@Injectable` decorator. This second
scenario was broken in Ivy.
In Ivy, previous to this commit, if a class to be instantiated did not have
its own `@Injectable` decorator and did not provide a constructor of
its own, then it would be created using `new` with no arguments -
i.e. falling back to the first scenario.
After this commit Ivy correctly uses the `ngInjectableDef` inherited
from the super-class to provide the `factory` for instantiating the
sub-class.

PR #30393 corrected behavior where Object.keys sometimes returns an `undefined` value. However, the types didn't reflect this in the code. That fix actually missed one value that could return `undefined`. This PR corrects this by casting the types to what they can be in IE 11. This ensures the code behaves as it should when this edge case comes up.

In some cases where multiple navigations happen to the same URL, the router will not process a given URL. In those cases, we fall into logic that resets state for the next navigation. One piece of this resetting is to set the `browserUrlTree` to the most recent `urlAfterRedirects`i.
However, there was bug in this logic because in some cases the `urlAfterRedirects` is a stale value. This happens any time a URL won't be processed, and the previous URL will also not be processed. This creates unpredictable behavior, not the least of which ends up being a broken `back` button.
This PR kicks off new navigations with the current value the router assumes is in the browser. All the logic around how to handle future navigations is based on this value compared to the current transition, so it's important to kick off all new navigations with the current value so in the edge case described above we don't end up with an old value being set into `browserUrlTree`.

* The `should throw if bindings in children of current view have changed` and `should NOT throw if bindings in ancestors of current view have changed` tests were removed, because there's not nice way of hitting the same code path with `TestBed` and doing the same assertion as with the raw instructions. I'm open to ideas on how we could do them.
