Improve libclang indexing support for class template specializations
in a few related ways:
- Don't recurse into instantiations of templates.
- Recurse into explicit specializations.
- Visit the template arguments of an explicit specialization or
explicit instantiation.
- Include template specialization arguments in the USRs for class
template specializations.
