Fix execute/20071219-1.c regression on H8 due to loss of REG_INC notes in peephole2.

gcc/
	* lra.c (add_auto_inc_notes): Remove function.
	* reload1.c (add_auto_inc_notes): Similarly.  Move into...
	* rtlanal.c (add_auto_inc_notes): New function.
	* rtl.h (add_auto_inc_notes): Add prototype.
	* recog.c (peep2_attempt): Scan and add REG_INC notes to new insns
	as needed.
