26554 up for out-of-line saves. Pass the actual pointer reg used to
26555 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
26556 function. Rearrange spe vars so code is similar to that
26557 elsewhere in this function. Don't update frame_off when spe
26558 save code will restore r11. Use emit_frame_save for spe and
26559 gpr saves. Consolidate darwin out-of-line gpr setup with that
26560 for other abis. Don't assume frame_offset is zero and frame
26561 reg is sp when setting up altivec reg saves, and calculate
26562 exact offset requirement.

26564 spe restore code. Consolidate darwin out-of-line gpr setup
