7656 save function. Choose r11 or r12 for vrsave reg when available for

7692 Set frame_reg_rtx to r11 whenever r11 is needed, and merge
7693 frame offset adjustment for out-of-line save with copy from sp.
7694 Simplify condition controlling whether cr is saved early or
7695 late. Use ptr_regno_for_savres to verify correct reg is set
7696 up for out-of-line saves. Pass the actual pointer reg used to
7697 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
7698 function. Rearrange spe vars so code is similar to that
7699 elsewhere in this function. Don't update frame_off when spe
7700 save code will restore r11. Use emit_frame_save for spe and
7701 gpr saves. Consolidate darwin out-of-line gpr setup with that

7703 reg is sp when setting up altivec reg saves, and calculate
7704 exact offset requirement.
