With dts bundles, `core.d.ts` will include an `EventListener` class as it's used in 303eae918d/packages/core/src/debug/debug_node.ts (L32)
This will conflict with the DOM EventListener, as anything in `core.d.ts` which is using the DOM EventListener will fallback in using the one defined in the same module and hence build will fail because their implementation is different.
With this change, we rename the local `EventListener` to `DebugEventListener`, the later one is non exported.

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.

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.

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.

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).

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

Queries can technically be also accessed within component templates
e.g.
```html
<my-comp [binding]="myQuery"></my-comp>
```
In that case the query with the property "myQuery" is accessed
statically and needs to be marked with `static: true`. There are
other edge cases that need to be handled as the template property
read doesn't necessarily resolve to the actual query property.
For example:
```html
<foo #myQuery></foo>
<my-comp [binding]="myQuery"></my-comp>
```
In this scenario the binding doesn't refer to the actual query
because the template reference variable takes precedence. The
query doesn't need to be marked with "static: true" this time.
This commit ensures that the `static-query` migration schematic
now handles this cases properly. Also template property reads
that access queries from within a `<ng-template>` are ignored
as these can't access the query before the view has been initialized.

case we need to check the setter declaration of the property and not the "getter". In order

based on the used operator token. There are three types of binary expressions:
1) Value assignment (using `=`). In that case only the setter is triggered.

This change moves the metadata for scope computations to a pure function
call that patches the scope references onto the module type. Because the

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

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

When an @NgModule is imported more than once in the testing module (for
example it appears in the imports of more than one module, or if it's
literally listed multiple times), then TestBed had a bug where the
providers for the module would be overridden many times.
This alone was problematic but would not break tests. However, the original
value of the providers field of the ngInjectorDef was saved each time, and
restored in the same order. Thus, if the provider array was [X], and
overrides were applied twice, then the override array would become
[X, X'] and then [X, X', X, X']. However, on the second override the state
[X, X'] would be stored as original. The array would then be restored to
[X] and then [X, X'].
Each test, therefore, would continue to double the size of the providers
array for the module, eventually exhausting the browser's memory.
This commit adds a Set to track when overrides have been applied to a module
and refrain from applying them more than once.

Prior to this change, recompilation of AOT-compiled components in TestBed may fail when template override is requested. That was happening due to the `styleUrls` field defined for a Component, thus switching its state to "requires resolution" (i.e. having external resources) at compile time. This change avoids this issue by storing styles and resetting `styleUrls` field before recompilation. Once compilation is done, saved styles are patched back onto Component def.

- Adds `property` instruction
- Does _NOT_ add compiler changes to accommodate `property` instruction, that will be a follow up PR.
- Updates `select` instruction to set the selected index in state.
- Adds dev mode assertions around the selected index state.

Currently when building an Angular project with `ngtsc`
and `flatModuleOutFile` enabled, the Ngtsc build will fail
if there are multiple source files as root file names.
Ngtsc and NGC currently determine the entry-point for multiple
root file names by looking for files ending with `/index.ts`.
This functionality is technically deprecated, but still supported
and currently breaks on Windows as the root file names are not
guaranteed to be normalized POSIX-like paths.
In order to make this logic more reliable in the future, this commit
also switches the shim generators and entry-point logic to the branded
path types. This ensures that we don't break this in the future.

forEach is slower as compared to a regular loop but more importantly
this change removes an anonymous function and thus makes stack traces
shorter and easier to read (important for perf analysis).

This commit removes code duplication where we had 2 versions of a
`flatten` utility. Moreover this change results in queries using
a non-recursive version of `flatten` which should result in a better
performance of query refresh operations.
