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.

Aaron Ballman 9ec96a2f3f Fix #pragma redefine_extname when there is a local variable of the same name. The local should not be renamed, only the externally-available declaration should be.

Alexander Musman 70e9f5fcb3 PR5172: Fix for a bug in pragma redefine_extname implementation:
it doesn't work correctly when a structure is declared before pragma
and then a function with the same name declared after pragma.
