cfgloop.h (struct loop): Remove unused "nodes" field.

	* cfgloop.h (struct loop): Remove unused "nodes" field.
	* timevar.def (TV_TREE_LOOP_BOUNDS): New.
	* tree-data-ref.c (find_data_references_in_loop): Use get_loop_body
	instead of calling flow_bb_inside_loop_p for every basic block
	in the function.
	* tree-ssa-loop.c (pass_record_bounds): Use TV_TREE_LOOP_BOUNDS.
