* rs6000-tdep.c (rs6000_pop_frame): Use PC_IN_CALL_DUMMY to test

	for call dummy instead of accessing stop_stack_dummy, which does
	not work if we `return' from a stop in a call dummy.
	(rs6000_gdbarch_init):  Use generic_save_dummy_frame_tos for
	dummy_frame_tos function to make PC_IN_CALL_DUMMY work.
