[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

declare double @llvm.sqrt.f64(double %f)
Turn MipsOptimizeMathLibCalls into a target-independent scalar transform ...so that it can be used for z too. Most of the code is the same. The only real change is to use TargetTransformInfo to test when a sqrt instruction is available. The pass is opt-in because at the moment it only handles sqrt. llvm-svn: 189097

[SystemZ] Fold more spills Add a mapping from register-based <INSN>R instructions to the corresponding memory-based <INSN>. Use it to cut down on the number of spill loads. Some instructions extend their operands from smaller fields, so this required a new TSFlags field to say how big the unextended operand is. This optimisation doesn't trigger for C(G)R and CL(G)R because in practice we always combine those instructions with a branch. Adding a test for every other case probably seems excessive, but it did catch a missed optimisation for DSGF (fixed in r185435). llvm-svn: 185529
