2731 Set frame_reg_rtx to r11 whenever r11 is needed, and merge

2733 Simplify condition controlling whether cr is saved early or
2734 late. Use ptr_regno_for_savres to verify correct reg is set
2735 up for out-of-line saves. Pass the actual pointer reg used to
2736 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
2737 function. Rearrange spe vars so code is similar to that
2738 elsewhere in this function. Don't update frame_off when spe
2739 save code will restore r11. Use emit_frame_save for spe and
2740 gpr saves. Consolidate darwin out-of-line gpr setup with that

2742 reg is sp when setting up altivec reg saves, and calculate
2743 exact offset requirement.
