Johnni Winther 52db62dd65 [cfe] Use MixinSuperStub
This CL adds stub for each concrete mixed in member into mixin
applications. The body of the stub calls the original member via
a super call.

This addition means that resolution of super access now use the
stub and not the original declaration as the target, which means
that it will be correct even when mixed in members are cloned. For
this reason, dart2js no longer needs to perform its own super
member resolution.

When a super call targets a mixin super stub (after cloning) it
can be optimized away by redirecting the call to the `stubTarget`
of the call. This optimization is performed in dart2js.

Since dart2js now uses the correct super target, its runtime
mixin application needs to avoid overriding members already
declared in the mixin application. These members are the
forwarding super stubs which ensure that correct runtime types
when members with covariant parameters are implemented.

Daco Harkes b6b82dd3ac [vm/ffi] Support nested structs
This CL adds support for nested structs in FFI calls, callbacks, and
memory loads and stores through the Struct classes itself.

Nesting empty structs and nesting a structs in themselves (directly or
indirectly) is reported as error.

This feature is almost fully implemented in the CFE transformation.

Because structs depend on the sizes of their nested structs, the structs
now need to be processed in topological order.

Field access to nested structs branches at runtime on making a derived
Pointer if the backing memory of the outer struct was a Pointer or
making a TypedDataView if the backing memory of the outer struct was
a TypedData.

Assigning to a nested struct is a byte for byte copy from the source.

The only changes in the VM are contained in the native calling
convention calculation which now recursively needs to reason about
fundamental types instead of just 1 struct deep.

Because of the amount of corner cases in the calling conventions that
need to be covered, the tests are generated, rather than hand-written.

ABIs tested on CQ: x64 (Linux, MacOS, Windows), ia32 (Linux, Windows),
arm (Android softFP, Linux hardFP), arm64 Android.
ABIs tested locally through Flutter: arm64 iOS.
ABIs not tested: ia32 Android (emulator), x64 iOS (simulator), arm iOS.

Johnni Winther 1930c07cd7 [cfe] Add flags to MethodInvocation and fileEndOffset to Block
The CL add a 'flags' to MethodInvocation with the properties isInvariant
and isBoundsSafe. The former is used for to marks safe calls in unified
collection encoding. Both can be used further by backends.

The CL also adds a 'fileEndOffset' to Block. This is current set for
block declared in used code.

Dmitry Stefantsov d54e2bb568 [cfe,ddc,dart2js,vm] Add NullType
This CL is the sum of the following 5 CLs:
* https://dart-review.googlesource.com/c/sdk/+/170342/
* https://dart-review.googlesource.com/c/sdk/+/170344/
* https://dart-review.googlesource.com/c/sdk/+/170345/
* https://dart-review.googlesource.com/c/sdk/+/170346/
* https://dart-review.googlesource.com/c/sdk/+/170347/

The reason for landing the 5 CLs as one CL is to prevent potential
troubles with bisecting over the branch because the change is fully
functional only with all 5 CLs.

Closes #40122.

The added test show that we generate a super call to the wrong target
in some forwarding stubs. The target should have been the mixed in
member but is instead the super member that it overrides.

Clement Skau c486a07b02 [VM] Fixes yield* exception handling in sync*.
This adds a mechanism similar to that used in async functions where
exceptions are caught in the synthetic code and passed into the
generated body to be rethrow'n.
This ensures the exception is throw'n from the same place as the
original yield*, as per the spec.
