Log message:
	* cfgloop.c (flow_loop_entry_edges_find, flow_loop_exit_edges_find,
	flow_loop_pre_header_scan, flow_loop_pre_header_find,
	flow_loop_scan): Removed.
	(flow_loop_dump): Do not dump removed fields.
	(flow_loop_free): Do not free removed fields.
	(flow_loops_find): Flags argument removed.  Do not call flow_loop_scan.
	(loop_exit_edge_p): New function.
	* cfgloop.h (struct loop): Removed fields pre_header, pre_header_edges,
	num_pre_header_edges, entry_edges, num_entries, exit_edges,
	num_exits, exits_doms.
	(LOOP_TREE, LOOP_PRE_HEADER, LOOP_ENTRY_EDGES, LOOP_EXIT_EDGES,
	LOOP_EDGES, LOOP_ALL): Removed.
	(flow_loop_scan): Declaration removed.
	(loop_exit_edge_p, mark_loop_exit_edges): Declare.
	* cfgloopmanip.c (create_loop_notes): Do not pass flags to
	flow_loops_find.
	* ifcvt.c (mark_loop_exit_edges): Moved to cfgloopanal.c.
	(if_convert): Call flow_loops_find and flow_loops_free
	when calling mark_loop_exit_edges.
	* cfgloopanal.c (mark_loop_exit_edges): Moved from
	ifcvt.c.  Removed the flow_loops_find, flow_loops_free and
	free_dominance_info calls.
	* loop-init.c (flow_loops_find): Ditto.
	* passes.c (rest_of_handle_branch_prob): Ditto.
	* lambda-code.c (perfect_nestify): Do not call flow_loops_find.
	* loop-unroll.c (analyze_insns_in_loop): Do not use
	EDGE_LOOP_EXIT.
	* predict.c (predict_loops): Do not call flow_loop_scan.
	Use get_loop_exit_edges.
	(tree_estimate_probability): Do not pass flags to flow_loops_find.
	* tree-if-conv.c (bb_with_exit_edge_p): Take loop as argument.
	Do not use EDGE_LOOP_EXIT.
	(tree_if_convert_cond_expr, if_convertible_modify_expr_p): Pass loop
	to bb_with_exit_edge_p.
	(if_convertible_loop_p): Do not call flow_loop_scan.  Use
	loop->single_exit.  Do not use EDGE_LOOP_EXIT.  Pass loop
	to bb_with_exit_edge_p.
	(combine_blocks): Pass loop to bb_with_exit_edge_p.  Do not use
	EDGE_LOOP_EXIT.
	* tree-loop-linear.c (linear_transform_loops): Do not call
	flow_loop_scan.  Use loop->single_exit.
	* tree-vect-analyze.c (vect_analyze_operations): Use loop->single_exit.
	(vect_analyze_loop_form): Do not call flow_loop_scan.
	* tree-vect-transform.c (vect_update_ivs_after_vectorizer): Use
	loop->single_exit.
	(vect_do_peeling_for_loop_bound): Use loop_preheader_edge and
	loop->single_exit.
	* tree-vectorizer.c (slpeel_update_phis_for_duplicate_loop,
	slpeel_make_loop_iterate_ntimes, slpeel_can_duplicate_loop_p,
	slpeel_tree_duplicate_loop_to_edge_cfg,
	slpeel_verify_cfg_after_peeling, slpeel_tree_peel_loop_to_edge):
	Use loop_preheader_edge and loop->single_exit.  Do not call
	flow_loop_scan.
