15431 Set frame_reg_rtx to r11 whenever r11 is needed, and merge
15432 frame offset adjustment for out-of-line save with copy from sp.
15433 Simplify condition controlling whether cr is saved early or
15434 late. Use ptr_regno_for_savres to verify correct reg is set
15435 up for out-of-line saves. Pass the actual pointer reg used to
15436 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
15437 function. Rearrange spe vars so code is similar to that
15438 elsewhere in this function. Don't update frame_off when spe
15439 save code will restore r11. Use emit_frame_save for spe and
15440 gpr saves. Consolidate darwin out-of-line gpr setup with that

15442 reg is sp when setting up altivec reg saves, and calculate
15443 exact offset requirement.
