7279 frame offset adjustment for out-of-line save with copy from sp.
7280 Simplify condition controlling whether cr is saved early or
7281 late. Use ptr_regno_for_savres to verify correct reg is set
7282 up for out-of-line saves. Pass the actual pointer reg used to
7283 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
7284 function. Rearrange spe vars so code is similar to that
7285 elsewhere in this function. Don't update frame_off when spe
7286 save code will restore r11. Use emit_frame_save for spe and
7287 gpr saves. Consolidate darwin out-of-line gpr setup with that

7289 reg is sp when setting up altivec reg saves, and calculate
7290 exact offset requirement.
