	* match.pd: Remove superfluous :c.
	* genmatch.c (simplify::id): Add member.
	(lower_commutative, lower_opt_convert, lower_cond, lower_for):
	Copy id.
	(current_id): New global.
	(dt_node::parent): Move from ...
	(dt_operand::parent): ... here.  Add for_id member.
	(is_a_helper <dt_operand *>::test): DT_TRUE is also a dt_operand.
	(decision_tree::find_node): Relax order requirement when
	merging DT_TRUE nodes to ones inbetween the current simplify
	and the one we try to merge with.  Add diagnostic whenever
	we need to enforce pattern order by not merging.
	(decision_tree::insert): Set current_id.
	(decision_tree::print_node): Dump parent node and for_id.
	(parser::last_id): Add member.
	(parser::push_simplify): Assign unique id.
