tree-loop-linear.c (gather_interchange_stats, [...]): Use loop_depth and loop_outer accessor functions.

	* tree-loop-linear.c (gather_interchange_stats, try_interchange_loops):
	Use loop_depth and loop_outer accessor functions.
	* tree-ssa-loop-im.c (outermost_invariant_loop, set_level,
	determine_invariantness_stmt, move_computations_stmt): Ditto.
	* cfgloopmanip.c (fix_bb_placement, fix_loop_placement, remove_path,
	add_loop, loopify, unloop, fix_loop_structure): Ditto.
	* tree-ssa-loop-manip.c (find_uses_to_rename_use): Ditto.
	* tree-scalar-evolution.c (interpret_loop_phi,
	compute_scalar_evolution_in_loop, analyze_scalar_evolution_in_loop,
	instantiate_parameters_1, scev_const_prop): Ditto.
	* cfghooks.c (make_forwarder_block): Ditto.
	* cfgloopanal.c (mark_irreducible_loops, mark_loop_exit_edges): Ditto.
	* modulo-sched.c (loop_canon_p): Ditto.
	* tree-vectorizer.c (slpeel_tree_duplicate_loop_to_edge_cfg,

	(flow_loop_nested_p, superloop_at_depth, flow_loop_free,
	add_bb_to_loop, remove_bb_from_loops, find_common_loop): Use the
	superloops vector instead of "pred" array.
	(establish_preds): Take father loop as an argument.  Initialize the
	superloops vector.
	(flow_loop_tree_node_add): Pass father loop to establish_preds.  Do not
	initialize loop->outer.
	(flow_loop_tree_node_remove): Truncate the superloops vector.
	* cfgloop.h (struct loop): Removed field "outer", fields "depth" and
	"pred" merged to "superloops" vector.
	(loop_depth, loop_outer): New.
	(fel_init): Use loop_outer.
