in a debug-info-bearing function has a debug location attached to it. Failure to do so causes an "!dbg attachment points at wrong subprogram for function" assertion failure when the inliner sets up inline scope info. rdar://problem/25878916 This reaplies r267320 without changes after fixing an issue in the OpenMP IR generator in clang. llvm-svn: 267370
