Fangrui Song 789a46f2d7 [CodeGenModule] Assume dso_local for -fpic -fno-semantic-interposition 
Summary:
Clang -fpic defaults to -fno-semantic-interposition (GCC -fpic defaults
to -fsemantic-interposition).
Users need to specify -fsemantic-interposition to get semantic
interposition behavior.

Semantic interposition is currently a best-effort feature. There may
still be some cases where it is not handled well.

Richard Smith 891fc7f37a Generalize "static data member instantiated" notification to cover variable templates too. 
While here, split the "point of instantiation changed" notification out from
it; these two really are orthogonal changes.
