[SystemZ] Optimize floating-point comparisons with zero This follows the same lines as the integer code. In the end it seemed easier to have a second 4-bit mask in TSFlags to specify the compare-like CC values. That eats one more TSFlags bit than adding a CCHasUnordered would have done, but it feels more concise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187883 91177308-0d34-0410-b5e6-96231b3b80d8
