Perform additional semantic checking of class template
specializations. In particular:
- Make sure class template specializations have a "template<>"
header, and complain if they don't.
- Make sure class template specializations are declared/defined
within a valid context. (e.g., you can't declare a specialization
std::vector<MyType> in the global namespace).
