* reload1.c: (init_reload): use HARD_FRAME_POINTER_REGNUM instead of
FRAME_POINTER_REGNUM.
(reload): Only prohibit elimination of HARD_FRAME_POINTER_REGNUM, not
FRAME_POINTER_REGNUM if frame_pointer_needed.  Never prohibit
elimination of FRAME_POINTER_REGNUM into HARD_FRAME_POINTER_REGNUM.
Mark HARD_FRAME_POINTER_REGNUM as live at the start of a block if
it is still needed after elimination.
(eliminate_regs): For non-local goto's, don't delete stores into the
hard frame pointer.
(eliminate_regs_in_insn): adjust comment.
(mark_not_eliminable): if frame_pointer_rtx and hard_frame_pointer_rtx
are not the same, then frame_pointer_rtx is eliminable;
hard_frame_pointer_rtx never is if it is set..
(order_regs_for_reload): HARD_FRAME_POINTER_REGNUM is a bad spill reg.
(choose_reload_regs): HARD_FRAME_POINTER_REGNUM is a bad choice.
