The `template-var-assignment` schematic currently complains if someone
assigns a value to a template variable. This will no longer work with Ivy, but
it should be totally fine to update a property of the template variable if it refers
to an object. This commit adds a test that ensures that we don't incorrectly report
any failure for such property writes in bound events.

Improves the failure messages for the `template-var-assignment` schematic. After manual
testing of the schematic it's not quite clear for developers what the failure message means
without any context. The schematic now also references a short markdown file mentioning
what needs to be changed, but eventually this document needs to be expanded with more
information and context of the reasoning behind this change within Ivy.

Previously, if a matching rootDir ended with a slash then the path
returned from `logicalPathOfFile()` would not start with a slash,
which is inconsistent.

The new styling algorithm in angular is designed to evaluate host
bindings stylinh priority in order of directive evaluation order. This,
however, does not work with respect to parent/sub-class directives
because sub-class host bindings are run after the parent host bindings
but still have priority. This patch ensures that the host styling bindings
for parent and sub-class components/directives are executed with respect
to the styling algorithm prioritization.

Prior to this change, any provider that was independently resolved using
its InjectableDef would not be considered when destroying the module it
was requested from. This commit provides a fix for this issue by storing
the resolved provider in the module's list of provider definitions.

Adds an overload to TestBed.get making parameters strongly typed and
deprecated previous signature that accepted types `any`. The function
still returns `any` to prevent build breakages, but eventually stronger
type checks will be added so a future Angular version will break builds
due to additional type checks.

While running `ng update @angular/core --next`, the following error would be displayed:
```
Cannot find module '....\node_modules\@angular\core\schematics\migrations\template-var-assignment\index'
```
This happened because the Schematics migration was referenced, but not included.
This commit fixes that bug by including the migration in the Bazel npm package dependencies.

Simply adds a `debug` property to the array of create opcodes while inside
`readCreateOpCodes` in i18n. This `debug` property has a property called `operations`
that is a human-readable list of operations that will be performed, as derived
from the op codes themselves, and the view it's acting upon.

This new interface will match classes whether they are abstract or
concrete. Casting as `AbstractType<MyConcrete>` will return a type that
isn't newable. This type will be used to match abstract classes in the
`get()` functions of `Injector` and `TestBed`.
Type isn't used yet so this isn't a breaking change.

The defineInjector function specifies its providers and imports array to
be optional, so if no providers/imports are present these keys may be
omitted. This commit updates the compiler to only generate the keys when
necessary.

Prior to this change, a module's imports and exports would be used verbatim
as an injectors' imports. This is detrimental for tree-shaking, as a
module's exports could reference declarations that would then prevent such
declarations from being eligible for tree-shaking.
Since an injector actually only needs NgModule references as its imports,
we may safely filter out any declarations from the list of module exports.
This makes them eligible for tree-shaking once again.
PR Close#29598
Prior to this change, all module metadata would be included in the
`defineNgModule` call that is set as the `ngModuleDef` field of module
types. Part of the metadata is scope information like declarations,
imports and exports that is used for computing the transitive module
scope in JIT environments, preventing those references from being
tree-shaken for production builds.
This change moves the metadata for scope computations to a pure function
call that patches the scope references onto the module type. Because the
function is marked pure, it may be tree-shaken out during production builds
such that references to declarations and exports are dropped, which in turn
allows for tree-shaken any declaration that is not otherwise referenced.

With the new API, where you can choose to only process the first
matching format, it is possible to process an entry-point multiple
times, if you pass in a different format each time.
Previously, ngcc would always try to process the typings files for
the entry-point along with processing the first format of the current
execution of ngcc. But this meant that it would be trying to process
the typings a second time.
Now we only process the typings if they have not already been
processed as part of processing another format in another
even if it was in a different execution of ngcc.

Currently our plan is to skip the publish, docgen, and update steps for this package.
During RC, we'll determine if the breaking change is too difficult for users, in which case we might restore the package for another major.

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
declaration's initializer becomes a binary expression with its rhs being
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
`ModuleWithProviders` object did not take the methods of such classes into
account.
Another edge-case with such intermediate variable was that static
properties would not be considered as class members. A testcase was added
to prevent regressions.

Previously we had to share code between upgrade/dynamic and upgrade/static
by symlinking the `src` folder, which allowed both packages to access
the upgrade/common files.
These symlinks are always problematic on Windows, where we had to run
a script to re-link them, and restore them.
This change uses Bazel packages to share the `upgrade/common` code,
which avoids the need for symlinking the `src` folder.
Also, the Windows specific scripts that fixup the symlinks have also
been removed as there is no more need for them.

method, so that it supports this kind of return type.

This commit introduces a mechanism for incremental compilation to the ngtsc
compiler.
Previously, incremental information was used in the construction of the
ts.Program for subsequent compilations, but was not used in ngtsc itself.
This commit adds an IncrementalState class, which tracks state between ngtsc
compilations. Currently, this supports skipping the TypeScript emit step
when the compiler can prove the contents of emit have not changed.
This is implemented for @Injectables as well as for files which don't
contain any Angular decorated types. These are the only files which can be
proven to be safe today.
See ngtsc/incremental/README.md for more details.

This commit adds support for compiling the same program repeatedly in a way
that's similar to how incremental builds work in a tool such as the CLI.
* support is added to the compiler entrypoint for reuse of the Program
object between compilations. This is the basis of the compiler's
incremental compilation model.
* support is added to wrap the CompilerHost the compiler creates and cache
ts.SourceFiles in between compilations.
* support is added to track when files are emitted, for assertion purposes.
* an 'exclude' section is added to the base tsconfig to prevent .d.ts
outputs from the first compilation from becoming inputs to any subsequent
compilations.

This commit adds a `tracePerformance` option for tsconfig.json. When
specified, it causes a JSON file with timing information from the ngtsc
compiler to be emitted at the specified path.
This tracing system is used to instrument the analysis/emit phases of
compilation, and will be useful in debugging future integration work with
@angular/cli.
See ngtsc/perf/README.md for more details.

Currently, ngtsc decides to use remote scoping if the compilation of a
component may create a cyclic import. This happens if there are two
components in a scope (say, A and B) and A directly uses B. During
compilation of B ngtsc will then note that if B were to use A, a cycle would
be generated, and so it will opt to use remote scoping for B.
ngtsc already uses the R3TargetBinder to correctly track the imports that
are actually required, for future cycle tracking. This commit expands that
usage to not trigger remote scoping unless B actually does consume A in its
template.

Prior to this change, if a navigation was ongoing and a new one came in, the router could get into a state where `router.currentNavigation` was `null` even though a navigation was executing. This change moves where we set the `currentNavigation` value so it's inside a `switchMap`. This solves the problem because the `finally` on the `switchMap` had been setting `currentNavigation` to `null` but the new `currentNavigation` value would have already been set. Essentially this was a timing problem and is resolved with this change.
