	(attempt_change): Added inc_reg parm and boolean result.  Move
	some tests to try_merge.  Added processing for reg_next_inc_use.
	(try_merge): Added boolean result and some test moved from
	attempt_change and parse_add_or_inc.
	(parse_add_or_inc): Move test to try_merge.  Improved debugging,
	and added code to support reg_next_inc_use.  Added more
	correctness tests.
	(rest_of_handle_auto_inc_dec): Changed df problem initialization
	and added code to support reg_next_inc_use.
