contained additional parenthesis or casts. This commit changes the
behavior to first unwrap the AST nodes to see past such insignificant
nodes, resolving the issue.

When compiling Angular classes, the compiler may decide to append statements with specific metadata that's only required for JIT. This includes things like decorator metadata as well as NgModule scope data.
When the compiler generates such calls, the call sites are marked with Uglify's PURE annotation, so the optimizer will remove them in production builds. However, Closure does not have the PURE (or similar) annotation. We have a utility function `noSideEffects` in the runtime for this purpose. This commit wraps `setClassMetadata` and `setNgModuleScope` function bodies in `noSideEffect` closures to allow Closure remove them.

The `TNode.cleanup` data structure can contain sequences of 4-element
sequence of entries (event handlers, directive outputs) mixed with
2-element sequence of entries (QueryList cleanup). Before this fix
we would always skip 4 elements in the `TNode.cleanup` while looking
up event handler cleanups. 4-element skips are not correct in case
of query cleanup presence and this commit corrects the algorithm to
jump 4 or 2 elements depending on a type of cleanup encountered.

The server used for testing on localhost has less optimizations (e.g.
serves uncompressed files), so we need to wait longer the ServiceWorker
to be loaded and registered to allow Lighthouse to reliably detect it,
especially on slower environments (e.g. CI).

If a component has its definition set by defineComponent (as opposed to
JIT getter), then it will generate a factory that uses directiveInject()
to retrieve its dependencies. This can be problematic in test code because
tests could use the injection utility before bootstrapping the component,
and directiveInject() relies on the view having been created.
This commit tweaks directiveInject() to fall back to inject() if the view
has not been created. This will allow injection to work in tests even if
it is called before the component is bootstrapped.
PR Close#29948
Previous to this commit, providing a component or directive in a test
module without @Injectable() would throw because the injectable factory
would not be found. Providing components in tests in addition to declaring
or importing them is not necessary, but it should not throw an error.
This commit ensures factory data is saved when component defs and directive
defs are created, which allows them to be processed by the module injector.
Note that bootstrapping is still required for this setup to work because
directiveInject() does not support cases where the view has not been
created. This case will be handled in a future commit.

We had a bug where event.preventDefault() was not always called if listeners
were coalesced. This is because we were overwriting the previous listener's
result every time we called the next listener, so listeners early in the chain
that returned false would be ignored and preventDefault would not be called.
This commit fixes that issue, so now preventDefault() is called if any listener
in a coalesced chain returns false. This brings us in line with View Engine
behavior.

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.

Overriding multi provider values (providers with `multi: true` flag) via TestBed require additional handling: all existing multi-provider values for the same token should be removed from the override list, so that they are not included into the final value of a given provider.

Because the styling context may be stored in a different location
and be apart of a sub array, reading the styling context each time
a host binding is evaluated is costly. This patch ensures that the
active styling context is cached so that multiple interactions with
styling bindings can easily retrieve the styling context efficiently.

The PWA score tests have been occasionally failing on CI recently
(possibly due to CI VM/network issues).
This commit temporarily disables them, until we investigate the
root-cause and/or put a work-around in place.
The PWA score tests are still run against the deployed versions (which
don't suffer as much) or PRs with public previews (as part of the
`test_aio_preview` job) and on upstream builds (as part of the
`deploy_aio` job).

Currently if there are multiple source files within a given
TypeScript source file, only the last template in the source
file is checked as we store templates in a `Map` with the
source file paths as keys.
This is problematic as multiple templates can live within the
same source file and we therefore accidentally overwrite
existing entries in the resolved templates map.

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`

In order to support multiple strategies for detecting the query timing, the

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).

Prior to this change, element attributes annotated with i18n- prefix were removed from element attribute list and processed separately by i18n-specific logic. This behavior is causing issues with directive matching, since attributes are not present in the list of attrs for matching purposes. This commit updates i18n logic to retain attributes in the main attribute list, thus allowing directive matching logic to work correctly.

In order to be backwards compatible with View Engine, Ivy should log
errors by default in the TestBed error handler rather than re-throwing
them. Re-throwing the errors is a breaking change that causes issues with
libraries like ngrx that have async behavior and custom error handling.
This logging approach has issues (for both VE and Ivy) because it can allow
tests to pass inappropriately if errors are thrown inside listeners. However,
since re-throwing would be breaking and requires a larger redesign, we should
wait until post-Ivy.

Previously, this check was done with bracket property access on the
global object: global['goog']
This will not be minified when Closure compiles this code, which:
1) breaks, because 'goog' will have been minified but the check won't have
taken that into consideration
2) causes build failures in g3, because the actual property 'goog' is
forbidden in some published JS code (to ensure obfuscation).
A TODO is added to validate that this logic is correct, as it's difficult to
test within the Angular repo.

So far using runtime i18n with ivy meant that you needed to use Closure and `goog.getMsg` (or a polyfill). This PR changes the compiler to output both closure & non-closure code, while the unused option will be tree-shaken by minifiers.
This means that if you use the Angular CLI with ivy and load a translations file, you can use i18n and the application will not throw at runtime.
For now it will not translate your application, but at least you can try ivy without having to remove all of your i18n code and configuration.
