Previously, the `URLS_TO_REDIRECT.txt` file was expected to separate
URLs by a `\t` character. This could easily been mistaken for a regular
space and would often result in test errors when updating the file.
This commit updates the `URLS_TO_REDIRECT.txt` file and the
corresponding test helpers to use `-->` (potentially surrounded by
whitespace) as a separator for the URLs. This also gives a hint about
the "from" --> "to" relationship of the redirect URL pair.

Previously, the `URLS_TO_REDIRECT.txt` file was expected to not contain
any empty lines. This could easily result in test errors when updating
the file, since it is common for IDEs/editors to automatically ensure
there is an empty line at the end of a saved file
([example failure][1]).
This commit updates the test helpers to be able to cope with empty or
whitespace-only lines in `URLS_TO_REDIRECT.txt` by ignoring such lines.

This adds string literals, number literals, `true`, `false`, `null` and
`undefined` to autocomplete results in templates.
For example, when completing an input of union type.
Component: `@Input('input') input!: 'a'|'b'|null;`
Template: `[input]="|"`
Provide `'a'`, `'b'`, and `null` as autocompletion entries.
Previously we did not include literal types because we only included
results from the component context (`ctx.`) and the template scope.
This is the second attempt at this. The first attmpet is in , then was
reverted in 75f881e078.
The `ViewportScroller` figures out which element to scroll into view using `document.getElementById`. The problem is that it won't find elements inside the shadow DOM.
These changes add some extra logic that goes through all the shadow roots to look for the element.

When creating the router state, the `RouteReuseStrategy#retrieve` should
only be called when `RouteReuseStrategy#shouldAttach` returns `true`.
That is, we should only retrieve a stored route when the reuse strategy
indicates that there is one stored and that it should be reattached.
This now matches the behavior in the route activation:

This situation can probably happen only when using
`HashLocationStrategy` and by manually changing hash that triggers a route
guard that returns a new `UrlTree`. Then hash in the browser might not
match the current route because navigation was canceled, while hash in
the URL remained set by the user.

When recognizing routes, the router merges nodes which map to the same
empty path config. This is because auxiliary outlets under empty path
parents need to match the parent config. This would result in two
outlet matches for that parent which need to be combined into a single
node: The regular 'primary' match and the match for the auxiliary outlet.
In addition, the children of the merged nodes should also be merged to
account for multiple levels of empty path parents.

With this commit, the language service will first try to locate a
pre-compiled style file with the same name when a `css` is provided in
the `styleUrls`. This prevents a missing resource diagnostic for when the
compiled file is not available in the language service environment and also
allows "go to definition" to go to that pre-compiled file.

The language service uses an elements attributes to determine if it
matches a directive in the component scope. We do this by accumulating
all attribute bindings and matching against the selectors for the
available directives. The compiler itself does a similar thing. In
addition, the compiler does not use the value of `BoundAttribute`s to
match directives (cdf1ea1951/packages/compiler/src/render3/view/util.ts (L174-L206)). This commit changes the language
service to also ignore bound attribute values for directive matching.

Previously, the `DefaultImportRecorder` interface was used as follows:
1. During the analysis phase, the default import declaration of an
identifier was recorded.
2. During the emit phase each emitted identifier would be recorded.
The information from step 1 would then be used to determine the
default import declaration of the identifier which would be
registered as used.
3. A TypeScript transform would taint all default imports that were
registered as used in step 2 such that the imports are not elided
by TypeScript.
In incremental compilations, a file may have to be emitted even if its
analysis data has been reused from the prior compilation. This would
mean that step 1 is not executed, resulting in a mismatch in step 2 and
ultimately in incorrectly eliding the default. This was mitigated by
storing the mapping from identifier to import declaration on the
`ts.SourceFile` instead of a member of `DefaultImportTracker` such that
it would also be visible to the `DefaultImportRecorder` of subsequent
compiles even if step 1 had not been executed.
Ultimately however, the information that is being recorded into the
`DefaultImportRecorder` has a longer lifetime than a single
`DefaultImportRecorder` instance, as that is only valid during a single
compilation whereas the identifier to import declaration mapping
outlives a single compilation. This commit replaces the registration of
this mapping by attaching the default import declaration on the output
AST node that captures the identifier. This enables the removal of
all of the `DefaultImportRecorder` usages throughout the analysis phase
together with the `DefaultImportRecorder` interface itself.

The Angular compiler has to actively keep default import statements
alive if they were only used in type-only positions, but have been
emitted as value expressions for DI purposes. A problem occurred in
incremental recompilations, where the relationship between an identifier
usage and its corresponding default import would not be considered. This
could result in the removal of the default import statement and caused
a `ReferenceError` at runtime.
This commit fixes the issue by storing the association from an
identifier to its default import declaration on the source file itself,
instead of within the `DefaultImportTracker` instance. The
`DefaultImportTracker` instance is only valid for a single compilation,
whereas the association from an identifier to a default import
declaration is valid as long as the `ts.SourceFile` is the same
instance.
A subsequent commit refactor the `DefaultImportTracker` to no longer
be responsible for registering the association, as its lifetime is
conceptually too short to do so.

The `emitDecoratorMetadata` compiler option does not have to be enabled
as Angular decorators are transformed by the AOT compiler. Having the
option enabled in our tests can hide issues around import preservation,
as with `emitDecoratorMetadata` enabled the TypeScript compiler itself
does not elide imports even if they are only used in type-positions.
This is unlike having `emitDecoratorMetadata` disabled, however; in that
case the Angular compiler has to actively trick TypeScript into
retaining default imports when an identifier in a type-only position has
been reified into a value position for DI purposes.
A subsequent commit addresses a bug in default import preservation
that relies on this flag being `false`.

When multiple occurrences of the same package exist within a single
TypeScript compilation unit, TypeScript deduplicates the source files
by introducing redirected source file proxies. Such proxies are
recreated during an incremental compilation even if the original
declaration file did not change, which caused the compiler not to reuse
any work from the prior compilation.
This commit changes the incremental driver to recognize a redirected
source file and treat them as their unredirected source file.

When an Ivy NgModule is imported into a View Engine build, it doesn't have
metadata.json files that describe it as an NgModule, so it appears to VE
builds as a plain, undecorated class. The error message shown in this
situation generic and confusing, since it recommends adding an @NgModule
annotation to a class from a library.
This commit adds special detection into the View Engine compiler to give a
more specific error message when an Ivy NgModule is imported.

Fix unexpected error when following the tutorial (when going through it with stricter type checking enforced). While (+) converts a string to an integer, it does not account for the possibility that `this.route.snapshot.paramMap.get('id')` could return null (type: string | null). Since this null case is not a practical outcome, it is a matter of types; switching from (+) to the `Number` function eliminates this issue, making the tutorial more robust.

In environments such as the Language Service where inline type-checking code
is not supported, the compiler would previously produce a diagnostic when a
template would require inlining to check. This happened whenever its
component class had generic parameters with bounds that could not be safely
reproduced in an external TCB. However, this created a bad user experience
for the Language Service, as its features would then not function with such
templates.
Instead, this commit changes the compiler to use the same strategy for
inline TCBs as it does for inline type constructors - falling back to `any`
for generic types when inlining isn't available. This allows the LS to
support such templates with slightly weaker type-checking semantics, which
a test verifies. There is still a case where components that aren't
exported require an inline TCB, and the compiler will still generate a
diagnostic if so.
