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.

Alexey Bataev 8cf35e4683 [OPENMP] Do not capture private variables in the target regions. 
Private variables are completely redefined in the outlined regions, so
we don't need to capture them. Patch adds this behavior to the
target-based regions.
