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
