[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

; There are two indirect fp128 slots, one at offset 224 (the first available
; byte after the outgoing arguments) and one immediately after it at 240.
; These slots should be set up outside the glued call sequence, so would
; normally use %f0/%f2 as the first available 128-bit pair. This choice
; is hard-coded in the FP128 tests.

[SystemZ] Add some generic (floating point support) load instructions. Add generic instructions for load complement, load negative and load positive for fp32 and fp64, and let isel prefer them. They do not clobber CC, and so give scheduler more freedom. SystemZElimCompare pass will convert them when it can to the CC-setting variants. Regression tests updated to expect the new opcodes in places where the old ones where used. New test case SystemZ/fp-cmp-05.ll checks that SystemZCompareElim.cpp can handle the new opcodes. README.txt updated (bullet removed). Note that fp128 is not yet handled, because it is relatively rare, and is a bit trickier, because of the fact that l.dfr would operate on the sign bit of one of the subregisters of a fp128, but we would not want to copy the other sub-reg in case src and dst regs are not the same.
