Instructions from __nodebug__ functions don't have file:line information even when inlined into no-nodebug functions. As a result, intrinsics (SSE and other) from <*intrin.h> clang headers _never_ have file:line information. With this change, an instruction without !dbg metadata gets one from the call instruction when inlined. Fixes PR19001. llvm-svn: 210459
