Prefer to expand mask for xor to -1, so we have a chance to turn it into a not. If it cannot be expanded, it will keep the old behaviour and try to shrink the constant. Part of enhancement for PR2191. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49280 91177308-0d34-0410-b5e6-96231b3b80d8
