7291 frame offset adjustment for out-of-line save with copy from sp.
7292 Simplify condition controlling whether cr is saved early or
7293 late. Use ptr_regno_for_savres to verify correct reg is set
7294 up for out-of-line saves. Pass the actual pointer reg used to
7295 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
7296 function. Rearrange spe vars so code is similar to that
7297 elsewhere in this function. Don't update frame_off when spe
7298 save code will restore r11. Use emit_frame_save for spe and
7299 gpr saves. Consolidate darwin out-of-line gpr setup with that
7300 for other abis. Don't assume frame_offset is zero and frame
7301 reg is sp when setting up altivec reg saves, and calculate
7302 exact offset requirement.
