Parsing, semantic analysis, and template instantiation for typename
specifiers that terminate in a simple-template-id, e.g.,
typename MetaFun::template apply<T1, T2>
Also, implement template instantiation for dependent
nested-name-specifiers that involve unresolved identifiers, e.g.,
typename T::type::type
