This adds checks for allocations and type values, and provides a compile
time error for type declarations, is-checks, and as-casts.

This relands 75a9579ea0.
The approach works as follows:
Step 1: Kernel transform. Under the closed world assumption compute the
set of selectors dispatched dynamically, then mark all procedures that don't
match any of those selectors as 'not-dispatched-dynamically'.
Step 2: VM backend. When building IR for a function if this function was
marked as not-dispatched-dynamically then omit type checks for any parameter
that is not marked as generic-covariant-impl, as such arguments are guaranteed
to be checked on the caller side (by front-end).

Alternatively to annotating individual procedures, I considered annotating Program node
with a set of dynamically dispatched selectors. Decoding and passing this information
around proved to be quite cumbersome in the "streaming" world, so I opted for a simpler
approach where all individual procedures are annotated.

From the docs of mixedInClass and mixin: the former is the direct thing that is
mixed in, but if it is a named mixin application it may not contain the actual
fields and procedures, instead the `.mixin` class does.

As requested in #31691 the incremental compiler should be able to
initialize its state from a previously generated dill file.
This CL introduces that functionally.
It is tested, but actual usage (e.g. proper invalidation of old files)
should live outside of the front-end (i.e. it's the callers responsibility).
One option would be for the caller to load the dill file and use the
included sources to invalidate changed files.
On my machine a from-scratch compile of dart2js takes ~5 seconds,
one initialized from such an output and with a single file invalidated
(though it actually hasn't changed) it takes ~1 second and the resulting
dill file is bit-perfect compared to the from-scratch compiled one.
Closes#31691.

Before any ASTs are constructed, a lookup happens to see if such a constructor exists, otherwise the AST replacement will not proceed, and even temporary ASTs will not be created: in this way we can add the test test_visitMethodInvocations_not_implicit_constructor.

Dart allows 'external' functions which are not connected to their body.
Calling such functions produces runtime error, but they should be accepted
at compile time. Test language_2/external_test verifies this behavior.
This CL fixes treeshaker/findNativeName to return 'null' instead of throwing
an error for 'external' functions without @ExternalName annotation (which
is used to specify native name).
