The flags on the fields are serialized as lists of flag names,
allowing for any combination of the flags in any order. Similar
technique is used in this CL to serialize the flags on Procedures and
VariableDeclarations. This is in the contrast with the previous
approach for those nodes, when the flags were the part of the
serialized name of the node (such as "static-method" for static
Procedures or "final" for final VariableDeclarations).

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.

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

This CL adds some infrastructure that makes it possible to defer the
inference of type arguments for a type alias which is used to specify
an instance creation:
class B<X, Y> {}
class C<X> implements B<String, X> {}
typedef T<X> = C<List<X>>;
void main() {
B<Object, Iterable<num>> c = T(); // Infer `T<num>()`.
}
The CL contains an implementation for type inference in the case
where the target is a non-redirecting constructor.
There is not yet an implementation of type inference for the case
where the type alias ultimately resolves to a redirecting factory
constructor, and the shadow nodes are eliminated as null.

This CL introduces dart_api_dl.h which exposes a subset of dart_api.h
and dart_native_api.h for dynamic linking at runtime through the FFI.
Dynamic linking is done through including dart_api_dl.cc in a shared
library and passing NativeApi.initializeApiDLData to the init function.
This CL also includes Native API versioning to deal with possible
version skew between native api version against which native libraries
are compiled and the version in the DartVM the code is run on.
The subset of symbols in the CL includes handle related symbols, error
related symbols, handle scope symbols, and native port sumbols.

The dill file has an index at the end. The last 4 bytes of that index is
a size that indicates how big the file is. This is done to support
concatenated dill files. If the dill is invalid and the size is read as 0
both the VM and the dart kernel reader will go into an infinite loop where
it allocates another list entry on every loop iteration (making the whole
loop not infinate because we will run out of ram soon enough).
This CL fixes the issue by checking the size to be possitive.

Add a kernel transformation which removes redundant casts and reduces
some casts to null checks. This transformation assumes that type
system is sound and subtyping relation is transitive. So in NNBD weak
mode this transformation is always correct. In NNBD strong mode
this transformation is correct only if opted-out libraries are not
allowed.
The following patterns are handled:
If S <: T (this includes S <: T? in weak mode)
S x; x as T => x
If S <: T? in strong mode
S x; x as T => (x == null) ? x as T : x
This kernel transformation is not specific to the VM and can be reused
by other back-ends such as dart2js and DDC.

Removes the Closure.clone() in sync* by adding an additional closure

- https://dart-review.googlesource.com/c/sdk/+/136190

- A new 'ShadowRewriter' transformer to do deep rewriting of
shadowed parameters.
Previous versions only rewrote the immediate sync* function, missing
references in nested rewritten functions.
Note: This CL is re-landing largely unchanged since the roll-blocking
issues suspected to be caused by this was later attributed to a
different set of changes.
I have independently re-run all failing external tests to verify
