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.
