When a class with a custom decorator is transpiled to ES5, it looks something like this:
```
var SomeClass = (function() {
function SomeClass() {...};
var SomeClass_1 = __decorate([Decorator()], SomeClass);
SomeClass = SomeClass_1;
return SomeClass;
})();
```
The problem is that if the class also has an Angular decorator that refers to the class itself
(e.g. `{provide: someToken, useClass: SomeClass}`), the generated `setClassMetadata` code will
be emitted after the IIFE, but will still refer to the intermediate `SomeClass_1` variable from
inside the IIFE. This happens, because we generate the `setClassMetadata` call directly from
the source AST which contains identifiers that TS will rename when it emits the ES5 code.
These changes resolve the issue by looking through the metadata AST and cloning any `Identifier`
that is referring to the class. Since TS doesn't have references to the clone, it won't rename
it when transpiling to ES5.
Fixes#39509.

This commit takes the `HybridVisitor` in the language service and gives it
the ability to return not just a node but the template context in which it
appears. In the future, more context regarding where a node appears in the
template might become necessary (ex: the microsyntax container for binding
nodes), and this refactoring enables that.
In the process, `HybridVisitor` is renamed and the concept of a
`TemplateTarget` interface is introduced to contain the results of this
operation.

This commit refactors the QuickInfo abstraction shared between the VE and
Ivy services and used to implement hover tooltips (quick info), which was
extracted from the VE code in commit faa81dc. The new DisplayParts
abstraction is more general and can be used to extract information needed by
various LS functions (e.g. autocompletion).
This commit effectively reverts faa81dc, returning the original code to the
VE implementation as the Ivy code is now diverged.

Previously, the documentation for each major Angular version was hosted
on each own Firebase project. This required creating a new project for
each major release and increased the administrative/maintenance cost.
Now that Firebase supports hosting [multiple websites][1] as part of the
same project, we are switching to deploying all major versions to sites
created on `angular-io` project.
This is part of the work needed to prepare angular.io for our
[new versioning/branching process][2] (also tracked in #39366).

This commit breaks up the code in `deploy-to-firebase.js` script, that
we use for deploying angular.io to production, to smaller functions
(instead of a monolithic block). This makes the script easier to
maintain and also makes testing individual operations easier.
The commit also updates the `deploy-to-firebase.spec.js` spec file to
take advantage of the standalone functions to speed up testing by
calling the corresponding function instead of having to spawn a new
process and run the `deploy-to-firebase.js` script with the `--dry-run`
flag.
NOTE: Before updating the tests, I verified that the updated
`deploy-to-firebase.js` script passed the old tests.

Different deployment modes (such as `archive` and `next`) are identified
by the different colors used in prominent elements of the page, such as
the topbar and the footer.
Previously, the necessary styles for creating such a deployment mode
"theme" were duplicated for each mode.
This commit simplifies the creation/modification of a deployment mode
theme by introducing a Sass mixin that generates the necessary styles

Previously, the `deploy-to-firebase.js` script and the accompanying
`deploy-to-firebase.spec.js` spec file were using the `origin` remote
alias in certain commands. This works fine on CI, where `origin` points

This commit ensures that the correct remote is used by explicitly
specifying it by the URL, thus ensuring that the tests will behave

Currently expressions `$event.foo()` and `this.$event.foo()`, as well as `$any(foo)` and
`this.$any(foo)`, are treated as the same expression by the compiler, because `this` is considered
the same implicit receiver as when the receiver is omitted. This introduces the following issues:
1. Any time something called `$any` is used, it'll be stripped away, leaving only the first parameter.
2. If something called `$event` is used anywhere in a template, it'll be preserved as `$event`,
rather than being rewritten to `ctx.$event`, causing the value to undefined at runtime. This
applies to listener, property and text bindings.
These changes resolve the first issue and part of the second one by preserving anything that
is accessed through `this`, even if it's one of the "special" ones like `$any` or `$event`.
Furthermore, these changes only expose the `$event` global variable inside event listeners,
whereas previously it was available everywhere.

To support recovery of malformed binding property names like `([a)`,
`[a`, or `()`, the binding parser needs to be more permissive w.r.t. the
kinds of bindings it can detect. This is difficult to do maintainably
with a regex, but is trivial with a "hand-rolled" string parser. This
commit refactors render3's binding attribute parsing to use this method
for multi-delimited bindings (namely via the `()`, `[]`, and `[()]`)
syntax, making the way recovery of malformed bindings in a future patch.
Note that we can keep using a regex for prefix-only binding syntax
(e.g. `bind-`, `ref-`) because validation of the binding is complete
once we have matched the prefix, and the only thing left to do is check
that the binding identifier is non-empty, which is trivial.

This is follow-up from [an earlier discussion](https://github.com/angular/angular/pull/39408#discussion_r511908358).
After some testing, it looks like the type of `Element.attributes` was correct in specifying that it
only has `TextAttribute` instances. This means that the extra checks that filter out `BoundAttribute`
instances from the array isn't necessary. There is another loop a bit further down that actually
extracts the bound i18n attributes.

Fix an issue that `markDirty()` will not trigger change detection.
The case is for example we have the following component.
```
export class AppComponent implements OnInit {
constructor(private router: Router) {}
ngOnInit() {
this.router.events
.pipe(filter((e) => e instanceof NavigationEnd))
.subscribe(() => ɵmarkDirty(this));
}
}
export class CounterComponent implements OnInit, OnDestroy {
ngOnInit() {
this.countSubject.pipe(takeUntil(this.destroy)).subscribe((count) => {
this.count = count;
ɵmarkDirty(this);
});
}
```
Then the app navigate from `AppComponent` to `CounterComponent`,
so there are 2 `markDirty()` call at in a row.
The `1st` call is from `AppComponent` when router changed, the
`2nd` call is from `CounterComponent.ngOnInit()`.
And the `markDirty()->scheduleTick()` code look like this
```
function scheduleTick(rootContext, flags) {
const nothingScheduled = rootContext.flags === 0 /* Empty */;
rootContext.flags |= flags;
if (nothingScheduled && rootContext.clean == _CLEAN_PROMISE) {
rootContext.schedule(() => {
...
if (rootContext.flags & RootContextFlags.DetectChanges)
rootContext.flags &= ~RootContextFlags.DetectChanges;
tickContext();
rootContext.clean = _CLEAN_PROMISE;
...
});
```
So in this case, the `1st` markDirty() will
1. set rootContext.flags = 1
2. before `tickContext()`, reset rootContext.flags = 0
3. inside `tickContext()`, it will call `CounterComponent.ngOnint()`,
so the `2nd` markDirty() is called.
4. and the `2nd` scheduleTick is called, `nothingScheduled` is true,
but rootContext.clean is not `_CLEAN_PROMISE` yet, since the `1st` markDirty tick
is still running.
5. So nowhere will reset the `rootContext.flags`.
6. then in the future, any other `markDirty()` call will not trigger the tick, since
`nothingScheduled` is always false.
So `nothingScheduled` means no tick is scheduled, `rootContext.clean === _CLEAN_PROMISE`
means no tick is running.
So we should set the flags to `rootContext` only when `no tick is scheudled or running`.

- incomplete arguments provided to a pipe

Angular-internal type definitions for Trusted Types were added in #39211.
When compiled using the Closure compiler with certain optimization
flags, identifiers from these type definitions (such as createPolicy)

Angular applications compiled in this way to fail to create a Trusted
