emit-rtl.c: Include rtl-iter.h. 

gcc/
	* emit-rtl.c: Include rtl-iter.h.
	(find_auto_inc): Turn from being a for_each_rtx callback to being
	a function that examines each subrtx itself.  Assume the first operand
	to an RTX_AUTOINC is the automodified register.
	(try_split): Update call accordingly.
