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.
