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> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208263 91177308-0d34-0410-b5e6-96231b3b80d8
