Use a pinned HTypeKnown on the receiver of the HInstanceEnvironment to
pin the type expression. When the the receiver has a wider type that
is legal for the type expression, this keeps the type expression at a
location where it is valid. Type expressions can still be hoisted if
the HTypeKnown is redundant and optimized away.

Today we make a half-hearted attempt to generate the correct default type arguments for parameter stubs. By the time we create them in the emitter we don't have enough information to fully replace all the type variables that might appear in a type parameter's bound. So instead we erase all type variables to "any".
By generating parameter stubs in SSA we can use existing RTI infrastructure to generate the correct recipes/bindings/evals. Instead of directly creating JS we create the appropriate SSA graph and let the normal function compiler do the heavy lifting.
There are benefits and drawbacks to this new approach:
1) The stub bodies go through the SSA optimizer so some parameters are abbreviated, some recurring nulls get replaced by a variable, etc. The net result is slightly more compact code.
2) We are now compiling code during the emitter phase. This is relatively fast (adds ~2% duration to the phase) but also requires deserializing some data we weren't previously using. This results in ~200MB more memory being used. I've changed the serialization layout a bit to try to mitigate this but some of it is unavoidable.

due to the low usage (there's only 1 result in google3 and 0 in

In order to reach parity with js_util, we expose operators
through an extension and do some partial renames in order
to make the member names sound better e.g. `equals` instead
of `equal`. We also expose the following from js_util:
- NullRejectionException
We don't expose `isJavaScriptArray` and `isJavaScriptSimpleObject`
as they can expressed through other forms of interop. There
was an esoteric bug where we needed these members for Firefox
in pkg:test, but the package no longer uses these members, so to
avoid increasing the API space too much, we do not export them.
For the same reason, we also don't expose `objectGetPrototypeOf`,
`objectPrototype`, `objectKeys`.
We don't expose `allowInteropCaptureThis` as it will take some
work to handle this in dart2wasm. That work is tracked in
https://github.com/dart-lang/sdk/issues/54381.
Lastly, `instanceof` and `instanceOfString` is moved to be on
`JSAny?`, as this operator is useful to avoid needing to
downcast to `JSObject` e.g. `any.instanceOfString('Window')`
instead of `any.typeofEquals('object') &&
(any as JSObject).instanceOfString('Window')`.
Extensions are reorganized and renamed to handle these changes.

When compiling a `while` in an `async` function, we need to allocate the
context for the `while` *before* compiling the `while` condition,
because any variables introduced in `while` condition will be stored in
the `while` context, rather than the parent context.
Instead of fixing where we allocate `while` context, we could update
`CaptureFinder` to add variables in the condition to the parent context,
and update `for` code generator, as it currently allocates `for` context
before the conditions.
I don't know if that has any advantages, for now it should be OK to
update `while` code generator.
`for` code generator allocates the context before the conditions and
does not have this issue.

This change reverts https://dart-review.googlesource.com/c/sdk/+/341020.
The reverted CL removed tests from `tests/language` that contained
legacy code (code with a language version less than 2.12). The primary
purpose of the removal was to unblock removal of legacy support from
the analyzer. It seemed safe to do because legacy code isn't supported
anymore, and no legacy code exists in google3 anymore. However,
several of those tests exercised important "weak mode" runtime
semantics of the web and VM platforms. See discussion at
https://dart-review.googlesource.com/c/sdk/+/341020/comments/bce31aa1_f5392ce1
for details.
This CL restores the deleted tests. Fortunately, since all the
restored tests are annotated with `Requirements=nnbd-weak`, they will
be skipped on the analyzer (thanks to
https://dart-review.googlesource.com/c/sdk/+/342080), so restoring
them no longer gets in the way of removing legacy support from the
analyzer.

The annotation `Requirements=nnbd-weak` controls prevents a test from
being run on a platform that doesn't have weak mode runtime semantics
(e.g. a program running with sound null safety).
In a previous CL
(https://dart-review.googlesource.com/c/sdk/+/341020), I removed
several tests from `tests/language` that contained legacy code, in
order to unblock removal of legacy support from the analyzer; those
tests all contained this annotation. However, after discussion with
Siggi, we've decided that it would be better to keep those tests
around for a while longer, because they exercise important runtime
behaviors of unsound null safety mode on the web and VM platforms, and
not all google3 code has been migrated off of unsound null safety mode
yet.
So, I intend to take a different approach to unblocking removal of
legacy support from the analyzer: stop running tests with the
annotation `Requirements=nnbd-weak` through the analyzer. This will
allow the tests removed in
https://dart-review.googlesource.com/c/sdk/+/341020 to be restored,
but it will have a side effect of causing a small number of additional
analyzer tests to be skipped. All those tests are benign to skip on
the analyzer (because they are purely concerned with runtime
semantics) except for one:
`superinterfaces_out_of_order_error_test.dart`.
This test doesn't have any runtime semantics at all; it merely checks
that the analyzer and CFE produce the correct errors for certain
compile-time type checks that have nothing to do with weak mode
runtime semantics.
So, to prevent a gap in test coverage when the analyzer begins
skipping tests annotated with `Requirements=nnbd-weak`, we need to
remove this annotation from
`superinterfaces_out_of_order_error_test.dart`.

The `Directory.current` setter has a `dynamic` parameter so that it
can accept either `String` or `Directory` arguments. (This is
asymmetric with the getter, which always returns a `Directory`.)
The corresponding `IOOverrides` callback, however, assumes that the
argument is always a `String`, and `Directory.current` passed its
`dynamic` argument through unchanged. Consequently, overriding
the `Directory.current` setter would result in a `TypeError` when
setting `Directory.current` to a `Directory` object.
Changing `IOOverrides.setCurrentDirectory` to use a `dynamic`
parameter would be a breaking change, so instead make the
`Directory.current` setter check the argument's runtime type before
passing it along.
