- For parameters of closurized members make sure to mark the virtual parameter as closurized where appropriate. Closurized parameters are treated as dynamic and this needs to propagate to all the virtual target's overrides. Previously only the concrete target was getting marked as closurized.
- For mixins defining an abstract member, foo, implementations of foo (either directly on the mixin target or superclasses of it) should propagate their types to the abstract foo as they are effectively overriding it. Calls to foo within the body of the mixin can only target the abstract foo with a virtual call. So that virtual target needs to reflect the types of all its overrides.
Tests have been added that capture both of these cases. The values here reflect the non-linearized algorithm but prior to these fixes the linearized algorithms showed a diff for both tests. After these changes there is no diff.
This fixes all failures referenced in b/277876666.

Let me know if any of this is unclear or if there's missing information.
Of course, you might not know that until you start trying to enhance the
support, but we can also refine the doc when issues are discovered. I'm
mostly just interested in helping you get started.

Create a compact version of StaticUse without fields that are often not provided. And intern instances of StaticUse as there are a lot of duplicates.
This should save >150MB in the emitter phase of Dart2JS.

When switching over a nullable expression, the `null` value should also
be handled for exhaustiveness.
The analyzer reports a lint for missing nulls, but the correction
producer was unable to fix the problem as it only adds missing enum
constants.
This change makes the fix producer add missing null cases.

- Rather than gating reads on URIs we've seen, gate logic on file scheme. Any URI with a 'file' scheme should be readable.
- Use unmapped URI when creating SourceFile. For providers that expand their URIS (e.g. BazelRootProvider) this will make sure we're using the more readable form rather than the prefix substituted version.

This saves the space for the `_identityHashCode` method in the
dispatch table and allows customizing `identityHashCode` for classes
not in `dart:core`.

A redirecting factory is normally encoded as something like
```
static factory •({required self::HelperClass bar = #C1}) → self::Bar
return new self::Foo::•(bar: bar);
```
which the CFE also expects to recreate its internal state when loading
a dill file.
The Finalizable transformation from FFI can change that to something
like:
```
static factory •({required self::HelperClass bar = #C1}) → self::Bar {
return block {
final synthesized self::Foo :expressionValueWrappedFinalizable = new self::Foo::•(bar: bar);
_in::reachabilityFence(bar);
} =>:expressionValueWrappedFinalizable;
}
```
though, which the CFE doesn't understand and subsequently crashes as
in https://github.com/flutter/flutter/issues/124369
This CL makes the CFE understand this transformed version,
fixing the crash.
TEST=Existing tests; added incremental compiler test.

Original change's description:
> [dart2js] Patch experimental inferrer (with linearized algorithm) into main inferrer.
>
> After this change for a large program we see:
> - 20% reduction in runtime (254s -> 202s)
> - 2% decrease in memory usage (7671.029MB -> 7524.901MB)
> - Code size decrease of <1% (214,788,150 bytes -> 214,757,445 bytes).
> - The k-limit of 6 refines imposed on the global inference algorithm is no longer hit for converging types. All but 15 types converge, down from 777 types that were hitting the k-limit before. This means we are likely generating better types/code for all 762 of those types.
> - More resilience to dynamic calls with lots of potential targets.

These dependency overrides prevent pub from getting confused about the
fact that our SDK development is in a mono-repo; that in turn allows
unit tests to be run from inside vscode using the standard test
integration.

`o is T` where `T` is an interface implemented by a class hierarchy
can be implemented as `o instanceof R` where `R` is the root of the
hierarchy. The common case is that `R` is a single implementation
class.
`is Record` and `is Type` now generally use `instanceof`.
