The CFE can invoke transformations despite having compile-time errors.
The async transform was crashing the compiler if it hits for-in
iterables that have an invalid type or never type.
In case of an invalid type, the program has a compile-time error and
won't be able to run propertly. So we'll replace the entire for-in with
an invalid expression statement if the iterable is an invalid
expression.
In case of a never type, the program should compile fine, which this CL
also fixes.
This makes the newly added tests no longer result in DartkCrash but
rather in a compile-time error (invalid expression) or runtime-error
(never type).

This changes the CFE expectation test suites to use unsound null safety
as default to avoid passing --enable-experiments=no-non-nullable to opt
out old test folders.
This change removes most test folders from the 'strong' tester, since
this now only supports sound null safety, which requires all libraries
to be opted in. Instead, the 'weak' tester now runs all test folders.
Additionally the 'outline' tester is changed to use unsound null safety
so that it call be used on all test folders.
The 'fast_strong' tester is removed since it should just be run locally
and it can be run by passing an option to the other testers.
References to non-existing 'shaker' folder has been removed from
testing.json.

Members declared in mixins are treated as if these were declared in
the class where they are mixed in. This means that use their types as
declared types, instead of including them in a combined member signature.
This failed in the case where a member was synthetically added to the
mixin class, because the types of these we wrongfully be handled as
declared types.
We now skip all synthetic members when reasoning about mixed in members
as declared members.

return let v = e in v is Future<FTV> ? await v ; v
where FTV is the future value type of the enclosing function.

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.

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.
