    * config/rs6000/rs6000.c (gen_frame_set): New function.
    (gen_frame_load, gen_frame_store): New functions.
    (rs6000_savres_rtx): Use the above.
    (rs6000_emit_epilogue, rs6000_emit_prologue): Here too.
    Correct mode used for CR2 in save/restore_world patterns.
    Don't emit instructions for eh_return frame unwind reg info.
