[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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181204 91177308-0d34-0410-b5e6-96231b3b80d8

[SystemZ] Allocate a second register scavenging slot This is another prerequisite for frame-to-frame MVC copies. I'll commit the patch that makes use of the slot separately. The downside of trying to test many corner cases with each of the available addressing modes is that a fair few tests need to account for the new frame layout. I do still think it's useful to have all these tests though, since it's something that wouldn't get much coverage otherwise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185698 91177308-0d34-0410-b5e6-96231b3b80d8
