This is nice for the instruction patterns, but it complicates min / max matching. The select doesn't have the correct type and would require looking through the bitcasts for the real float operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@224092 91177308-0d34-0410-b5e6-96231b3b80d8
