Apparently, we have strong mode tests in tests/language_strong, and all tests
here in tests/language are spec mode tests. This means that several of the above
are "acceptable". Do we have a way to make that status visible here, apart from
maybe adding "acceptable" to the comment?

I think the individual implementations should simply decide that it's ok to fail
on them, with an "OK". (As I did for dart2js).

 covariant_override_test: CompileTimeError # Issue 28167
 
 # Runtime negative test. No static errors or warnings.
