record loops in execution order

	* graphite-scop-detection.c (record_loop_in_sese): New.
	(gather_bbs::before_dom_children): Call record_loop_in_sese.
	(build_scops): Remove call to build_sese_loop_nests.
	* sese.c (sese_record_loop): Remove.
	(build_sese_loop_nests): Remove.
	(new_sese_info): Remove region->loops.
	(free_sese_info): Same.
	* sese.h (sese_contains_loop): Same.
	(build_sese_loop_nests): Remove.
	(sese_contains_loop): Remove.
