This commit provides a replacement for `$location`. The new service is written in Angular, and can be consumed into existing applications by using the downgraded version
of the provider.
Prior to this addition, applications upgrading from AngularJS to Angular could get into a situation where AngularJS wanted to control the URL, and would often parse or se
rialize the URL in a different way than Angular. Additionally, AngularJS was alerted to URL changes only through the `$digest` cycle. This provided a buggy feedback loop
from Angular to AngularJS.
With this new `LocationUpgradeProvider`, the `$location` methods and events are provided in Angular, and use Angular APIs to make updates to the URL. Additionally, change
s to the URL made by other parts of the Angular framework (such as the Router) will be listened for and will cause events to fire in AngularJS, but will no longer attempt
to update the URL (since it was already updated by the Angular framework).
This centralizes URL reads and writes to Angular and should help provide an easier path to upgrading AngularJS applications to Angular.

This abstract class (and AngularJSUrlCodec) are used for serializing and deserializing pieces of a URL string. AngularJS had a different way of doing this than Angular, and using this class in conjunction with the LocationUpgradeService an application can have control over how AngularJS URLs are serialized and deserialized.

When using the `history` API, setting a new `state` and retrieving it does not pass a `===` test to the object used to set the state. In other words, `history.state` is always a copy. This change makes the `MockPlatformLocation` behave in the same way.

This feature adds an `onUrlChange` to Angular's `Location` class. This is useful to track all updates coming from anywhere in the framework. Without this method, it's difficult (or impossible) to track updates run through `location.go()` or `location.replaceState()` as the browser doesn't publish events when `history.pushState()` or `.replaceState()` are run.

AngularJS's `$location` service doesn't have a direct counterpart in Angular. This is largely because the `Location` service in Angular was pulled out of the `Router`, but was not purpose-built to stand on its own.

Previously there wasn't a way to retrieve `history.state` from the `Location` service. The only time the framework exposed this value was in navigation events. This meant if you weren't using the Angular router, there wasn't a way to get access to this `history.state` value other than going directly to the DOM.
This PR adds an API to retrieve the value of `history.state`. This will be useful and needed to provide a backwards-compatible `Location` service that can emulate AngularJS's `$location` service since we will need to be able to read the state data in order to produce AngularJS location transition events.
This feature will additionally be useful to any application that wants to access state data through Angular rather than going directly to the DOM APIs.

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.

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.

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.

This commit adds support for template type-checking a pipe binding which
previously was not handled by the type-checking engine. In compatibility
mode, the arguments to transform() are not checked and the type returned

of the pipe.

PR Close#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.

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
produce the `LocalModuleScope`, and thus was handled by the
`LocalModuleScopeRegistry`.
However, the template type-checker also needs information about registered
directives, outside of the NgModule scope determinations. Rather than
reuse the scope registry for an unintended purpose, this commit introduces
new abstractions for metadata registration and lookups in a separate
'metadata' package, which the scope registry implements.
This paves the way for a future commit to make use of this metadata for the
template type-checking system.

for this is that '#' references are non-linear - a reference can be used

Accommodating this required refactoring the type-checking code generator to

Previous to this change, we assumed embedded views could only be created after
their parent template node had completed processing. As a result, we only set
up query logic for containers after directives on the node were created.
However, this assumption didn't take into account the case where a directive
on a template node could create views in its constructor.
This commit fixes query logic to work with views created in constructors.
In that case, we need to create a query container before the new view is
rendered so query results in the view aren't lost. But since the query container
is created before directives have completed processing, we also have to ensure
that query results gathered later on the template node are inserted before that
query container. Otherwise, query results in embedded views will clobber query
results on template nodes.
This splice mode may be slightly slower than the normal matching for queries on
containers, but we should only fall back to this strategy in the edge case where
views are created in constructors. (We should encourage developers to create
views in ngOnInit instead).

Introduces a new strategy for the `static-query` schematic that
is enabled by default. In order to provide a migration that works
for the most Angular applications and makes the upgrade as easy
as possible, the template strategy leverages the view engine
Angular compiler logic in order to determine the query timing
that is currently used within applications using view engine.
PR Close#29815
The `@angular/compiler` package currently contains the logic for determining whether
given queries are used statically or dynamically. This logic would be necessary in order
to build a schematic that leverages the Angular compiler API's in order to simulate the
query timing based on what ViewEngine computed at compilation-time/runtime.
Exporting the logic that is necessary to detect the timing should not affect the public
API as the `@angular/compiler` package is denoted as private in `PUBLIC_API.md`
PR Close#29815
In order to support multiple strategies for detecting the query timing, the
query usage logic has been moved into a query usage strategy.

`NodeJsSyncHost` is no longer provided by BuilderContext in
architect v2, and its usage caused subtle path resolution issues
in Windows.
This PR cleans up `@angular/bazel` builder to use all native path
and fs methods.

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).
