7673 Set frame_reg_rtx to r11 whenever r11 is needed, and merge
7674 frame offset adjustment for out-of-line save with copy from sp.
7675 Simplify condition controlling whether cr is saved early or
7676 late. Use ptr_regno_for_savres to verify correct reg is set
7677 up for out-of-line saves. Pass the actual pointer reg used to
7678 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
7679 function. Rearrange spe vars so code is similar to that
7680 elsewhere in this function. Don't update frame_off when spe
7681 save code will restore r11. Use emit_frame_save for spe and
7682 gpr saves. Consolidate darwin out-of-line gpr setup with that

7684 reg is sp when setting up altivec reg saves, and calculate
7685 exact offset requirement.
