Note: This is a reland of https://dart-review.googlesource.com/c/sdk/+/150343
Adds a new SDK hash to kernels and the VM which is optionally checked
to verify kernels are built for the same SDK as the VM.
This helps catch incompatibilities that are currently causing
subtle bugs and (not so subtle) crashes.
The SDK hash is encoded in kernels as a new field in components.
The hash is derived from the 10 byte git short hash.
This new check can be disabled via:
tools/gn.py ... --no-verify-sdk-hash
This CL bumps the min. (and max.) supported kernel format version,
making the VM backwards incompatible from this point back.
This also bumps the min. and current ABI version.

If a user program installs custom signal handling for SIGINT,
the DartDev instance may exit before its child, potentially causing
confusing behavior and 'zombie' children. By ignoring these signals in
DartDev, the DartDev instance will only exit once its child process
exits.

If 'growable' argument of List.filled factory invocation is known at
compile time we can replace it with more specialized constructors
creating growable or fixed-size lists. This results in a more accurate
inferred type and more efficient code which uses the created list.

This CL adds --trace-precompiler-to option which generates a machine readable
precompiler trace (list of all compiled functions and their dependencies).
It also expands package:vm_snapshot_analysis with tools for reading and
analysing this trace.
For example snapshot_analysis explain dynamic-calls command allows
to list all dynamic calls sorted by their impact on the size of the AOT
snapshot.

This was noticed when running the benchmarks/Calls/dart/Calls.dart with
sound-null-safety.
The only fix that was needed is to swap the argument order, but I also changed
to add the type promotion to make these errors stand out statically.

I don't understand why it falls into the runZonedGuarded() error handler instead of being caught by `on AbortCompletion`.
It seems somehow related to the fact that we throw AbortCompletion inside an async function, but before any `await`.
IIRC we now execute this portion immediately, and actually return a Future instance only when we reach the first `await`.
Maybe this somehow affects the try/catch.

This CL adds support for type inference on type aliased invocations of
factory constructors, redirected as well as non-redirected, and it adds
some tests using this feature.
Additionally, this CL resolves a couple of issues that arose when the
directory nonfunction_type_aliases was migrated to null-safety (by
means of two single line fixes, in 'usage*_test.dart').
Still missing: The shadow nodes should be eliminated in
_unaliasTypeAliasedConstructorInvocations and
_unaliasTypeAliasedFactoryInvocations, this will be done in a separate
CL.
