GlobalOpt: fix an issue where CXAAtExitFn points to a deleted function. CXAAtExitFn was set outside a loop and before optimizations where functions can be deleted. This patch will set CXAAtExitFn inside the loop and after optimizations. Seg fault when running LTO because of accesses to a deleted function. rdar://problem/13838828 llvm-svn: 181838

IR: Don't allow non-default visibility on local linkage Visibilities of `hidden` and `protected` are meaningless for symbols with local linkage. - Change the assembler to reject non-default visibility on symbols with local linkage. - Change the bitcode reader to auto-upgrade `hidden` and `protected` to `default` when the linkage is local. - Update LangRef. <rdar://problem/16141113> llvm-svn: 208263
