  Changed paths:
    M clang/lib/Sema/Sema.cpp
    M clang/lib/Sema/SemaTemplateInstantiate.cpp
    M clang/lib/Sema/SemaTemplateInstantiateDecl.cpp

  Log Message:
  -----------
  Ensure that we don't leave behind "InstantiatingSpecialization" entries
after destroying an InstantiatingTemplate object.

This previously caused us to (silently!) bail out of class template
instantiation, thinking we'd produced an error, in some corner cases.
