[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

[SystemZ] Optimize sign-extends of vector setccs Normal (sext (setcc ...)) sequences are optimised into (select_cc ..., -1, 0) by DAGCombiner::visitSIGN_EXTEND. However, this is deliberately not done for vectors, and after vector type legalization we have (sext_inreg (setcc ...)) instead. I wondered about trying to extend DAGCombiner to handle this case too, but it seemed to be a loss on some other targets I tried, even those for which SETCC isn't "legal" and SELECT_CC is. llvm-svn: 186149

[SystemZ] Optimize sign-extends of vector setccs Normal (sext (setcc ...)) sequences are optimised into (select_cc ..., -1, 0) by DAGCombiner::visitSIGN_EXTEND. However, this is deliberately not done for vectors, and after vector type legalization we have (sext_inreg (setcc ...)) instead. I wondered about trying to extend DAGCombiner to handle this case too, but it seemed to be a loss on some other targets I tried, even those for which SETCC isn't "legal" and SELECT_CC is. llvm-svn: 186149
