* 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.
