This ensures that frame-based unwinding will continue to work when calling a noreturn function; there is not much use having the caller's frame pointer saved if you don't also have the caller's program counter. Patch by James Clarke. Differential Revision: https://reviews.llvm.org/D68542 llvm-svn: 373907
