[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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@233688 91177308-0d34-0410-b5e6-96231b3b80d8
