  Log Message:
  -----------
  [Clang] Profile the NNS of UnresolvedUsingType and CXXThisType correctly in concept hashing (#199617)

They were sometimes incorrect because the written type doesn't contain
an NNS which contains template parameters we're interested in.

No release note because the bug broke MS STL and I want to backport it
to the last 22.x release

Fixes https://github.com/llvm/llvm-project/issues/198663

(cherry picked from commit 06ffb655904657e847854eee1c7c76ccdc75b254)
