Duncan P. N. Exon Smith b80de1012a 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.

Manman Ren b3c52fb45b 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.
