 	* tm-rs6000.h (BELIEVE_PCC_PROMOTION): Define, since AIX cc gets
	it right.
	(aix_framedata): added nosavedpc field.
	(SAVED_PC_AFTER_CALL): Don't try to optimize; just call
	read_register.
	(FRAMELESS_FUNCTION_INVOCATION): Pass second argument of 0.
	(FRAME_SAVED_PC): If PC not saved, use SAVED_PC_AFTER_CALL.
	* rs6000-tdep.c (skip_prologue): Handle gcc generated stfd
	instructions as function_frame_info does.  Expand special case of
	st r31,-4(r1) to be st r31,NUM(r1), since gcc can generate offsets
	other than -4.
	(pop_frame): Add 4 rather than sizeof (int) to avoid host
	dependence.
	(function_frame_info): Set frameless if the function has no frame,
	and set nosavedpc if the PC was not saved.  Handle gcc generated
	stfd 31,-4(31); st 31, -12(31) correctly.
	(frameless_function_invocation): New second argument pcsaved; if 0
	return whether the function has a frame, if 1 return whether the
	function saved PC.
	(frame_initial_stack_address): Correct typo: cache registers for
	callee_fi, not for fi, (avoids reading garbage memory locations).
