[PATCH] Fix _savef* on powerpc*-ibm-aix*

[Alan Modra]

The _savef* functions need to be called before the stack pointer is
adjusted.  Since Jakub's 2003-07-16 change, the stack adjustment happens
right at the start of the prologue when current_function_calls_eh_return,
so we can't use _savef*.

I've been playing with defining FP_SAVE_INLINE for powerpc64-linux,
which is how I ran into the problem..

	* config/rs6000/rs6000.c (rs6000_emit_prologue): Save fp regs inline
	if current_function_calls_eh_return.
