14622 up for out-of-line saves. Pass the actual pointer reg used to
14623 rs6000_emit_savres_rtx so rtl matches insns in out-of-line

14625 elsewhere in this function. Don't update frame_off when spe
14626 save code will restore r11. Use emit_frame_save for spe and
14627 gpr saves. Consolidate darwin out-of-line gpr setup with that

14629 reg is sp when setting up altivec reg saves, and calculate
14630 exact offset requirement.
