[SystemZ] Register compare-and-branch support This patch adds support for the CRJ and CGRJ instructions. Support for the immediate forms will be a separate patch. The architecture has a large number of comparison instructions. I think it's generally better to concentrate on using the "best" comparison instruction first and foremost, then only use something like CRJ if CR really was the natual choice of comparison instruction. The patch therefore opportunistically converts separate CR and BRC instructions into a single CRJ while emitting instructions in ISelLowering. llvm-svn: 182764

; Test all condition-code masks that are relevant for CRJ.
