Currently if a consumer does something like the following, the object literal will be shared across the two elements and any instances of the component template. The same applies to array literals:
```
<div [someDirective]="{}"></div>
<div [someDirective]="{}"></div>
```
These changes make it so that we generate a pure function even if an object is constant so that each instance gets its own object.
Note that the original design for this fix included moving the pure function factories into the `consts` array. In the process of doing so I realized that pure function are also used inside of directive host bindings which means that we don't have access to the `consts`.
These changes also:
* Fix an issue that meant that the `pureFunction0` instruction could only be run during creation mode.
* Make the `getConstant` utility slightly more convenient to use. This isn't strictly required for these changes to work, but I had made it as a part of a larger refactor that I ended up reverting.

In order to speed up bazel build performance delete all rxjs d.ts files
that reference rxjs-compat.
For all ts_library and ng_module rules Bazel generates tsconfig.json file
that explicitly lists all d.ts files found in required npm package.
In case of rxjs, this means that tsconfig contains all d.ts files that
reference rxjs-compat package, which is an interop/backwards compatibility
package not installed in angular/angular repo.
But because tsconfig contains these d.ts files, tsc will try to resolve
them and silently fail. All these lookups are quite expensive and not
cached. This causes significant slowdown of the build under bazel.
This change removes all of these problematic rxjs d.ts files via an npm
postinstall hook. This is not ideal because it solves the problem only
for our repo, but it's a good start.
Build perf improvements per target:
//packages/core/src/reflect:reflect 5sec => 3 sec
//packages/core:core 17sec => 12 sec
//packages/router:router 30sec => 8 sec

Prior to this change, setting style prop value to undefined or empty string would not result in resetting prop value in case the style prop is defined using [style.prop.px] syntax. The problem is that the check for empty value (and thus reseting the value) considered successful only in case of `null` value. This commit updates the check to use `isStylingValueDefined` function that also checks for undefined and empty string.

The reflection hosts have been updated to support the following
code forms, which were found in some minified library code:
* The class IIFE not being wrapped in parentheses.
* Calls to `__decorate()` being combined with the IIFE return statement.
PR Close#33777
Previously we only removed `__decorate()` calls that looked like:
```
SomeClass = __decorate(...);
```
But in some minified scenarios this call gets wrapped up with the
return statement of the IIFE.
```
return SomeClass = __decorate(...);
```
This is now removed also, leaving just the return statement:
```
return SomeClass;
```

The `dist/` directory has a duplicate `package.json` pointing to the
same files, which (under certain configurations) can causes ngcc to try

This commit adds a default ngcc config for `ng2-dragula` to ignore the

Prior to this change, ComponentFactory.create function invocation in Ivy retained the content of the host element (in case host element reference or CSS seelctor is provided as an argument). This behavior is different in View Engine, where the content of the host element was cleared, except for the case when ShadowDom encapsulation is used (to make sure native slot projection works). This commit aligns Ivy and View Engine and makes sure the host element is cleared before component content insertion.

During incremental compilations, ngtsc needs to know which metadata
from a previous compilation can be reused, versus which metadata has to
be recomputed as some dependency was updated. Changes to
directives/components should cause the NgModule in which they are
declared to be recompiled, as the NgModule's compilation is dependent
on its directives/components.
When a dependent source file of a directive/component is updated,
however, a more subtle dependency should also cause to NgModule's source
file to be invalidated. During the reconciliation of state from a
previous compilation into the new program, the component's source file
is invalidated because one of its dependency has changed, ergo the
NgModule needs to be invalidated as well. Up until now, this implicit
dependency was not imposed on the NgModule. Additionally, any change to
a dependent file may influence the module scope to change, so all
components within the module must be invalidated as well.
This commit fixes the bug by introducing additional file dependencies,
as to ensure a proper rebuild of the module scope and its components.

When the Angular compiler is operated through the ngc binary in watch
mode, changing a template in an external file would not cause the
component to be recompiled if Ivy is enabled.
There was a problem with how a cached compiler host was present that was
unaware of the changed resources, therefore failing to trigger a
recompilation of a component whenever its template changes. This commit
fixes the issue by ensuring that information about modified resources is
correctly available to the cached compiler host.

The `ngInjectableDef` property was renamed to `ɵprov`, but core must
still support both because there are published libraries that use the
older term.
We are only interested in such properties that are defined directly on
the type being injected, not on base classes. So there is a check that
the defintion is specifically for the given type.
Previously if you tried to inject a class that had `ngInjectableDef` but
also inherited `ɵprov` then the check would fail on the `ɵprov` property
and never even try the `ngInjectableDef` property resulting in a failed
injection.
This commit fixes this by attempting to find each of the properties
independently.

Since #33321, Angular packages have been persisted on each build as
CircleCI build artifacts (`.tgz` files), which can be used to install
dependencies on a project (for the purpose of testing or trying out a
change before a PR being merged and without having to build the packages
from source locally).
Previously, only packages published to npm under the `@angular` scope
were persisted as build artifacts.
This commit adds the `zone.js` package to the list of persisted
packages.

In #33046, internal uses of `zone.js` were switched to reference it
directly from source (built with Bazel) instead of npm. As a result, the
necessary scripts were updated to build `zone.js` as necessary. However,
some `integration/**/debug-test.sh` scripts were missed (apparently
because they are not used on CI, but only locally as helpers for
debugging the integration projects).
This commit updates the `scripts/build-packages-dist.sh` script to also
build `zone.js`, so that other scripts (such as the various
`debug-test.sh` scripts) can use it.

Most of the use of `document` in the framework is within
the DI so they just inject the `DOCUMENT` token and are done.
Ivy is special because it does not rely upon the DI and must
get hold of the document some other way. There are a limited
number of places relevant to ivy that currently consume a global
document object.
The solution is modelled on the `LOCALE_ID` approach, which has
`getLocaleId()` and `setLocaleId()` top-level functions for ivy (see
`core/src/render3/i18n.ts`). In the rest of Angular (i.e. using DI) the
`LOCALE_ID` token has a provider that also calls setLocaleId() to
ensure that ivy has the same value.
This commit defines `getDocument()` and `setDocument() `top-level
functions for ivy. Wherever ivy needs the global `document`, it calls
`getDocument()` instead. Each of the platforms (e.g. Browser, Server,
WebWorker) have providers for `DOCUMENT`. In each of those providers
they also call `setDocument()` accordingly.

It looks like there was a typo when it originally was
written. As it works right now, the `beforeEach` and
`afterEach` cancel each other out. But then
`ensureDocument()` is called anyway in the `withBody()`
function.
With this change there is no need to call `ensureDocument() in the
`withBody() function.

Previously the renderers were fixed so that they inserted extra
"adjacent" statements after the last static property of classes.
In order to help the build-optimizer (in Angular CLI) to be able to
tree-shake classes effectively, these statements should also appear
after any helper calls, such as `__decorate()`.
This commit moves the computation of this positioning into the
`NgccReflectionHost` via the `getEndOfClass()` method, which
returns the last statement that is related to the class.

While overriding providers in Ivy TestBed (via TestBed.overrideProvider call), the old providers were retained in the list, since the override takes precedence. However, presence of providers in the list might have side-effect: if a provider has the `ngOnDestroy` lifecycle hook, this hook will be registered and invoked later (when component is destroyed). This commit updates TestBed logic to clear provider list by removing the ones which have overrides.
