* cfgloop.h: Include vec-prim.h.

	(enum li_flags): Remove LI_ONLY_OLD.
	(loop_iterator): Changed.
	(fel_next, fel_init): Iterate over loop tree.
	(FOR_EACH_LOOP_BREAK): New macro.
	* loop-unswitch.c (unswitch_loops): Do not pass LI_ONLY_OLD to
	FOR_EACH_LOOP.
	* tree-ssa-loop-unswitch.c (tree_ssa_unswitch_loops): Ditto.
	* modulo-sched.c (sms_schedule): Ditto.
	* tree-vectorizer.c (vectorize_loops): Ditto.
	* doc/loop.texi: Update information on loop numbering and behavior of
	FOR_EACH_LOOP wrto new loops.
	* tree-scalar-evolution.c (compute_overall_effect_of_inner_loop,
	add_to_evolution_1): Test nestedness of loops instead of comparing
	their numbers.
	* tree-chrec.c (chrec_fold_plus_poly_poly,
	chrec_fold_multiply_poly_poly, chrec_evaluate,
	hide_evolution_in_other_loops_than_loop, chrec_component_in_loop_num,
	reset_evolution_in_loop): Ditto.
	* Makefile.in (CFGLOOP_H): Add vecprim.h dependency.
