This appears to have broken at least the windows build bots due to compile errors in the predicate that didn't simply supress the overload. I'm not sure what the fix is, and the bots have been broken for a long time now so I'm just reverting until Michael can figure out a fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225064 91177308-0d34-0410-b5e6-96231b3b80d8
