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

Use "weak alias" instead of "alias weak" Before this patch we had @a = weak global ... but @b = alias weak ... The patch changes aliases to look more like global variables. Looking at some really old code suggests that the reason was that the old bison based parser had a reduction for alias linkages and another one for global variable linkages. Putting the alias first avoided the reduce/reduce conflict. The days of the old .ll parser are long gone. The new one parses just "linkage" and a later check is responsible for deciding if a linkage is valid in a given context. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214355 91177308-0d34-0410-b5e6-96231b3b80d8
