This commit enhances the `CompileFn`, which is used to process each
entry-point, to support running a passed-in callback (and wait for it to
complete) before proceeding with writing the transformed files to disk.
This functionality is currently not used. In a subsequent commit, it
will be used for passing info from worker processes to the master
process that will allow ngcc to recover when a worker process crashes in
the middle of processing a task.

This commit adds support for stopping processing an in-progress task
and moving it back to the list of pending tasks.

a worker process crashes in the middle of processing a task.

Previously, ngcc would run in parallel mode (using the
`ClusterExecutor`) when there were at least 2 CPU cores (and all other
requirements where met). On systems with just 2 CPU cores, this meant
there would only be one worker process (since one CPU core is always
reserved for the master process). In these cases, the tasks would still
be processed serially (on the one worker process), but we would also pay
the overhead of communicating between the master and worker processes.
This commit fixes this by only running in parallel mode if there are
more than 2 CPU cores (i.e. at least 2 worker processes).

Previously, the "Compiling <entryPoint>" log message was printed before
starting to analyze and transform files, but after creating the
`EntryPointBundle` (which includes creating the TS program).
Since creating the `EntryPointBundle` involves some work, it is more
accurate to move the log message before creating the bundle.

This reverts commit d669429bd26dbd753584c331a6d7aa44a4d1f3ee.
The Angular CLI relies upon deep imports into `@angular/localize`. In this
case it relies upon the `source_file_utils.ts` file being in its previous
position.
In `master` (i.e. v10) the CLI will update its import to cope but we need
to revert for 9.1.x.

If there's an error during the first creation pass of a `TView`, the data structure may be corrupted which will cause framework assertion failures downstream which can mask the user's error. These changes add a new flag to the `TView` that indicates whether the first creation pass was successful, and if it wasn't we try re-create the `TView`.
Fixes#31221.

An enum declaration in TypeScript code will be emitted into JavaScript
as a regular variable declaration, with the enum members being declared
inside an IIFE. For ngcc to support interpreting such variable
declarations as enum declarations with its members, ngcc needs to
recognize the enum declaration emit structure and extract all member
from the statements in the IIFE.
This commit extends the `ConcreteDeclaration` structure in the
`ReflectionHost` abstraction to be able to capture the enum members
on a variable declaration, as a substitute for the original
`ts.EnumDeclaration` as it existed in TypeScript code. The static
interpreter has been extended to handle the extracted enum members
as it would have done for `ts.EnumDeclaration`.

Prior to this change, animations-related runtime logic assumed that the @HostBinding and @HostListener with synthetic (animations) props are used for Components only. However having @HostBinding and @HostListener with synthetic props on Directives is also supported by View Engine.

This reverts commit 1756cced4a59bc1185653c6c9b8f661636fd6116.
The reason for this revert is because of the change being too risky for

breaking change and can only be apart of the next release.

When module overrides (via `TestBed.overrideModule`) are present, it might affect all modules that import (even transitively) an overridden one. For all affected modules we need to recalculate their scopes for a given test run and restore original scopes at the end. Prior to this change, we were recalculating module scopes only for components that are used in a test, without taking into account module hierarchy. This commit updates Ivy TestBed logic to calculate all potentially affected modules are reset cached scopes information for them (so that scopes are recalculated as needed).

Prior to this commit unbound attributes were treated as possible inputs to structural directives. Since structural directives can only accepts inputs defined using microsyntax expression (e.g. `<div *dir="exp">`), such unbound attributes should not be considered as inputs. This commit aligns Ivy and View Engine behavior and avoids using unbound attributes as inputs to structural directives.

Based on the migration guide, provided classes which don't have
either `@Injectable`, `@Directive`, `@Component` or `@Pipe` need
to be migrated.
This is not correct as provided classes with an `@NgModule` also
have a factory function that can be read by the r3 injector. It's
unclear in which cases the `@NgModule` decorator is used for
provided classes, but this scenario has been reported.
Either we fix this in the migration, or we make sure to report
this as unsupported in the Ivy compiler.

The cached file-system was implemented to speed up ngcc
processing, but in reality most files are not accessed many times
and there is no noticeable degradation in speed by removing it.
Benchmarking `ngcc -l debug` for AIO on a local machine
gave a range of 196-236 seconds with the cache and 197-224
seconds without the cache.
Moreover, when running in parallel mode, ngcc has a separate
file cache for each process. This results in excess memory usage.
Notably the master process, which only does analysis of entry-points
holds on to up to 500Mb for AIO when using the cache compared to
only around 30Mb when not using the cache.
Finally, the file-system cache being incorrectly primed with file
contents before being processed has been the cause of a number
of bugs. For example https://github.com/angular/angular-cli/issues/16860#issuecomment-614694269.

This commit fixes how the language service evaluates the compatibility
of types to work with arbitrary union types. As a result, compatibility
checks are now more strict and can catch similarities or differences
more clearly.
```
number|string == string|null // OK
number|string == number // OK
number|string == null // not comparable
number == string // not comparable
```
Using Ivy as a backend should provide these diagnoses for free, but we
can backfill them for now.

The change in e041ac6f0d8c519d104601b2b49c008721c074b7
to support sending unlocker process output to the main ngcc
console output prevents messages require that the main process
relinquishes the event-loop to allow the `stdout.on()` handler to
run. This results in none of the messages being written when ngcc
is run in `--no-async` mode, and some messages failing to be
written if the main process is killed (e.g. ctrl-C).
It appears that the problem with Windows and detached processes
is known - see https://github.com/nodejs/node/issues/3596#issuecomment-250890218.
But in the meantime, this commit is a workaround, where non-Windows
`inherit` the main process `stdout` while on Windows it reverts
to the async handler approach, which is better than nothing.

When formatting a time with the `b` or `B` format codes, the rendered
string was not correctly handling day periods that spanned midnight.
Instead the logic was falling back to the default case of `AM`.
Now the logic has been updated so that it matches times that are within
a day period that spans midnight, so it will now render the correct
output, such as `at night` in the case of English.
Applications that are using either `formatDate()` or `DatePipe` and any

The current ngcc lock-file strategy spawns a new process in order to
capture a potential `SIGINT` and remove the lock-file. For more
information see #35861.
Previously, this unlocker process was spawned as soon as the `LockFile`
was instantiated in order to have it available as soon as possible
(given that spawning a process is an asynchronous operation). Since the
`LockFile` was instantiated and passed to the `Executor`, this meant
that an unlocker process was spawned for each cluster worker, when
running ngcc in parallel mode. These processes were not needed, since
the `LockFile` was not used in cluster workers, but we still had to pay
the overhead of each process' own memory and V8 instance.
(NOTE: This overhead was small compared to the memory consumed by ngcc's
normal operations, but still unnecessary.)
This commit avoids the extra processes by only spawning an unlocker
process when running on the cluster master process and not on worker
processes.
