[SystemZ] Add CodeGen test cases This adds all CodeGen tests for the SystemZ target. This version of the patch incorporates feedback from a review by Sean Silva. Thanks to all reviewers! Patch by Richard Sandiford. llvm-svn: 181204

; Test variable-sized allocas and addresses based on them in cases where
; stack arguments are needed.
;
[SystemZ] Use zeroing form of RISBG for some AND sequences RISBG can handle some ANDs for which no AND IMMEDIATE exists. It also acts as a three-operand AND for some cases where an AND IMMEDIATE could be used instead. It might be worth adding a pass to replace RISBG with AND IMMEDIATE in cases where the register operands end up being the same and where AND IMMEDIATE is smaller. llvm-svn: 186072

[SystemZ] Postpone NI->RISBG conversion to convertToThreeAddress() r186399 aggressively used the RISBG instruction for immediate ANDs, both because it can handle some values that AND IMMEDIATE can't, and because it allows the destination register to be different from the source. I realized later while implementing the distinct-ops support that it would be better to leave the choice up to convertToThreeAddress() instead. The AND IMMEDIATE form is shorter and is less likely to be cracked. This is a problem for 32-bit ANDs because we assume that all 32-bit operations will leave the high word untouched, whereas RISBG used in this way will either clear the high word or copy it from the source register. The patch uses the z196 instruction RISBLG for this instead. This means that z10 will be restricted to NILL, NILH and NILF for 32-bit ANDs, but I think that should be OK for now. Although we're using z10 as the base architecture, the optimization work is going to be focused more on z196 and zEC12. llvm-svn: 187492
