[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 64-bit unsigned comparisons in which the second operand is constant.

[SystemZ] Add unsigned compare-and-branch instructions For some reason I never got around to adding these at the same time as the signed versions. No idea why. I'm not sure whether this SystemZII::BranchC* stuff is useful, or whether it should just be replaced with an "is normal" flag. I'll leave that for later though. There are some boundary conditions that can be tweaked, such as preferring unsigned comparisons for equality with [128, 256), and "<= 255" over "< 256", but again I'll leave those for a separate patch. llvm-svn: 190930

; Check a value near the low end of the range. We use signed forms for

[SystemZ] Provide basic TargetTransformInfo implementation This hooks up the TargetTransformInfo machinery for SystemZ, and provides an implementation of getIntImmCost. In addition, the patch adds the isLegalICmpImmediate and isLegalAddImmediate TargetLowering overrides, and updates a couple of test cases where we now generate slightly better code. llvm-svn: 233688
