[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
