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.

Bill Wendling 3789171972 We are not able to bitcast a pointer to an integral value. 
Two return types are not equivalent if one is a pointer and the other is an
integral. This is because we cannot bitcast a pointer to an integral value.
