This is mostly aimed at the NEON logical operations and MOVI/MVNI (since they accept weird shifts which are more naturally understandable in hex notation). Also changes BRK/HINT etc, which is probably a neutral change, but easier than the alternative. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207634 91177308-0d34-0410-b5e6-96231b3b80d8
