What kind of test failures are you seeing, exactly?
Btw, I think it should be `TryAnnotateTypeOrScopeToken(AllowImplicitTypename)`
instead of `()`; that's an optional parameter, but one that is relevant to
`ParseDeclarationSpecifiers()`.
Do we maybe also need to do `TryAnnotateTypeConstraint()` as well?
