[PATCH] D35027: [PowerPC] Reduce register pressure by not materializing a constant just for use as an index register for X-Form loads/stores

sfertile added a comment.

Regarding the isIntS16Immediate change, the function is duplicated in PPCISelDAGToDAG.cpp as well. I suggest we leave it as is in this patch, and then in a separate patch common up the definitions and change it to use an int16_t argument. That keeps this patch focused on only doing a single thing, and puts the code cleanup in its own NFC patch.
