in one place (since the name changes and/or disappears as you go
towards inner frames), so we only call get_frame_saved_regs on
the current frame. This is directly in contradiction to the
usage below, which assumes that registers used in a frame must be
saved in a lower (more interior) frame. This change is a result
of working on a register window machine; get_frame_saved_regs
always returns the registers saved within a frame, within the
context (register namespace) of that frame. */
