stmt.c: (expand_goto): Set hard_frame_pointer_rtx when restoring the frame.
* stmt.c: (expand_goto): Set hard_frame_pointer_rtx when restoring
the frame. Use it when restoring other registers.
(expand_end_bindings): ARG_POINTER_REGNUM will be eliminated into
HARD_FRAME_POINTER_REGNUM, not FRAME_POINTER_REGNUM; adjust code accordingly.
