[SystemZ] Make more use of TMHH This originally came about after noticing that InstCombine turns some of the TMHH (icmp (and...), ...) tests into plain comparisons. Since there is no instruction to compare with a 64-bit immediate, TMHH is generally better than an ordered comparison for the cases that it can handle. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197238 91177308-0d34-0410-b5e6-96231b3b80d8
