[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

[SystemZ] Enable unaligned accesses The code to distinguish between unaligned and aligned addresses was already there, so this is mostly just a switch-on-and-test process. llvm-svn: 182920
