7222 Set frame_reg_rtx to r11 whenever r11 is needed, and merge

7224 Simplify condition controlling whether cr is saved early or
7225 late. Use ptr_regno_for_savres to verify correct reg is set
7226 up for out-of-line saves. Pass the actual pointer reg used to
7227 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
7228 function. Rearrange spe vars so code is similar to that
7229 elsewhere in this function. Don't update frame_off when spe
7230 save code will restore r11. Use emit_frame_save for spe and
7231 gpr saves. Consolidate darwin out-of-line gpr setup with that

7233 reg is sp when setting up altivec reg saves, and calculate
7234 exact offset requirement.
