Olivier Combe 2b44be984e fix(ivy): i18n should not alloc expando slots when there is no new var (#31451)
`i18nStart` was calling `allocExpando` even if there was 0 new variable created.
This created a new expando instruction with the value 0 which was later interpreted as the start of a new expando block instead of just skipping 0 instructions.

crisbeto 989ebcbb62 fix(ivy): inconsistent value returned by DebugNode.context (#31442)
Fixes Ivy's return value for `DebugNode.context` not being consistent for the case where there is both a structural directive and a component on a node. In `ViewEngine` the instance of the component would be returned, whereas in Ivy the context of the directive is returned.

Also adds a couple of extra test cases for how `DebugNode.context` deals with directives.

Paths can be mapped directly to files, which was not being taken

Pete Bacon Darwin a581773887 perf(ivy): ngcc - only find dependencies when targeting a single entry-point (#30525)
Previously, ngcc had to walk the entire `node_modules` tree looking for
entry-points, even if it only needed to process a single target entry-point
and its dependencies.

This added up to a few seconds to each execution of ngcc, which is noticeable
when being run via the CLI integration.

Now, if an entry-point target is provided, only that target and its entry-points
are considered rather than the whole folder tree.

Pete Bacon Darwin 7f2330a968 perf(ivy): ngcc - add a cache to the FileSystem (#30525)
When profiling ngcc it is notable that a large amount of time
is spent dealing with an exception that is thrown (and handled
internally by fs) when checking the existence of a file.

We check file existence a lot in both finding entry-points
and when TS is compiling code. This commit adds a simple
cached `FileSystem`, which wraps a real `FileSystem` delegate.
This will reduce the number of calls through to `fs.exists()` and
`fs.readFile()` on the delegate.

Initial benchmarks indicate that the cache is miss to hit ratio
for `exists()` is about 2:1, which means that we save about 1/3
of the calls to `fs.existsSync()`.

Note that this implements a "non-expiring" cache, so it is not suitable
for a long lived `FileSystem`, where files may be modified externally.
The cache will be updated if a file is changed or moved via
calls to `FileSystem` methods but it will not be aware of changes
to the files system from outside the `FileSystem` service.

For ngcc we must create a new `FileSystem` service
for each run of `mainNgcc` and ensure that all file operations
(including TS compilation) use the `FileSystem` service.
This ensures that it is very unlikely that a file will change
externally during `mainNgcc` processing.

Pete Bacon Darwin 98a68ad3e7 fix(ivy): handle namespaced imports correctly (#31367)
The ngcc tool adds namespaced imports to files when compiling. The ngtsc
tooling was not processing types correctly when they were imported via
such namespaces. For example:

```
export declare class SomeModule {
    static withOptions(...): ModuleWithProviders<ɵngcc1.BaseModule>;
```

In this case the `BaseModule` was being incorrectly attributed to coming
from the current module rather than the imported module, represented by
`ɵngcc1`.

crisbeto c0955975f4 feat(core): add automatic migration from Renderer to Renderer2 (#30936)
Adds a schematic and tslint rule that automatically migrate the consumer from `Renderer` to `Renderer2`. Supports:
* Renaming imports.
* Renaming property and method argument types.
* Casting to `Renderer`.
* Mapping all of the methods from the `Renderer` to `Renderer2`.

Note that some of the `Renderer` methods don't map cleanly between renderers. In these cases the migration adds a helper function at the bottom of the file which ensures that we generate valid code with the same return value as before. E.g. here's what the migration for `createText` looks like.

Before:
```
class SomeComponent {
  createAndAddText() {
    const node = this._renderer.createText(this._element.nativeElement, 'hello');
    node.textContent += ' world';
  }
}
```

After:
```
class SomeComponent {
  createAndAddText() {
    const node = __rendererCreateTextHelper(this._renderer, this._element.nativeElement, 'hello');
    node.textContent += ' world';
  }
}

function __rendererCreateTextHelper(renderer: any, parent: any, value: any) {
  const node = renderer.createText(value);
  if (parent) {
    renderer.appendChild(parent, node);
  }
  return node;

crisbeto 02491a6ce8 refactor(ivy): move classMap interpolation logic internally (#31211)
Adds the new `classMapInterpolate1` through `classMapInterpolate8` instructions which handle interpolations inside the `class` attribute and moves the interpolation logic internally. This allows us to remove the `interpolationX` instructions in a follow-up PR.

These changes also add an error if an interpolation is encountered inside a `style` tag (e.g. `style="width: {{value}}"`). Up until now this would actually generate valid instructions, because `styleMap` goes through the same code path as `classMap` which does support interpolation. At runtime, however, `styleMap` would set invalid styles that look like `<div style="0:w;1:i;2:d;3:t;4:h;5::;7:1;">`. In `ViewEngine` interpolations inside `style` weren't supported either, however there we'd output invalid styles like `<div style="unsafe">`, even if the content was trusted.

JoostK dca713c087 test(ivy): verify equality of ngBaseDef metadata between compiler and core (#31210)
There's no build time dependency from @angular/core to @angular/compiler,
so core can't directly refer to compiler types. To overcome this limitation,
there's a facade layer defined in the compiler and duplicated in core,
such that during runtime all types will correctly align.

There's a testcase in the compiler that verifies that all such facade types
are compatible across core and compiler, such that the core types can't get
misaligned with the actual definitions in the compiler. This suite of
tests were missing the `R3BaseMetadataFacade` facade type, so it was possible
for this type to get out of sync.

JoostK eb6281f5b4 fix(ivy): include type parameter for `ngBaseDef` declaration (#31210)
When a class uses Angular decorators such as `@Input`, `@Output` and
friends without an Angular class decorator, they are compiled into a
static `ngBaseDef` field on the class, with the TypeScript declaration
of the class being altered to declare the `ngBaseDef` field to be of type
`ɵɵBaseDef`. This type however requires a generic type parameter that
corresponds with the type of the class, however the compiler did not
provide this type parameter. As a result, compiling a program where such
invalid `ngBaseDef` declarations are present will result in compilation
errors.

This commit fixes the problem by providing the generic type parameter.

Without this change when using UrlTree redirects in `urlUpdateStrategy="eager"`, the URL would get updated to the target location, then redirected. This resulted in having an additional entry in the `history` and thus the `back` button would be broken (going back would land on the URL causing a new redirect).

Additionally, there was a bug where the redirect, even without `urlUpdateStrategy="eager"`, could create a history with too many entries. This was due to kicking off a new navigation within the navigation cancelling logic. With this PR the new navigation is pushed to the next tick with a `setTimeout`, allowing the page being redirected from to be cancelled before starting a new navigation.

George Kalpakas 5306330d85 test(service-worker): better simulate opaque requests (#30977)
Previously, opaque responses where handled a little differently than
other responses from the mock server. More specifically, they were not
tracked (so no assertions could be made for them) and their
[`Body` mixin][1] methods (such as `arrayBuffer()`, `json()`, `text()`)
would throw an error due to `body` being `null`.

This commit ensures opaque responses are also captured on the mock
server and also changes `Body` mixin methods to better simulate the
[spec'd behavior][2].

(These improvements will be necessary to test caching of opaque
responses in a subsequent commit.)

Kristiyan Kostadinov f2360aab9d fix(ivy): incorrect namespace for root node created through ViewContainerRef (#31232)
Currently in Ivy whenever we encounter a new namespace, we set it in the global state so that all subsequent nodes are created under the same namespace. Next time a template is run the namespace will be reset back to HTML.

This breaks down if the last node that was rendered was under the SVG or MathML namespace and we create a component through `ViewContainerRef.create`, because the next template function hasn't run yet and it hasn't had the chance to update the namespace. The result is that the root node of the new component will retain the wrong namespace and may not end up rendering at all (e.g. if we're trying to show a `div` inside the SVG namespace). This issue has the potential to affect a lot of apps, because all components inserted through the router also go through `ViewContainerRef.create`.
