(analyze_all_data_dependences): Initialize and free the loop_nest. (free_dependence_relations): Do not free loop_nest. (build_rdg): Pass in the loop_nest, datarefs, and dependence_relations. (free_rdg): Also free the data on edges. * tree-data-ref.h (build_rdg): Update declaration. (compute_data_dependences_for_loop): Same. * tree-if-conv.c (if_convertible_loop_p_1): Pass in the loop_nest. (if_convertible_loop_p): Allocate and free loop_nest. * tree-loop-distribution.c (rdg_flag_loop_exits): Free conds. (free_rdg_components): VEC_free components. (distribute_loop): Update call to build_rdg. Allocate and free loop_nest, datarefs, and dependence_relations. * tree-loop-linear.c (linear_transform_loops): Allocate and free loop_nest. * tree-parloops.c (loop_parallel_p): Same. * tree-predcom.c (tree_predictive_commoning_loop): Same. * tree-vect-data-refs.c (vect_analyze_data_refs): Pass to compute_data_dependences_for_loop a pointer to LOOP_VINFO_LOOP_NEST. * tree-vect-loop.c (new_loop_vec_info): Initialize LOOP_VINFO_LOOP_NEST. (destroy_loop_vec_info): Free LOOP_VINFO_MAY_ALIAS_DDRS and LOOP_VINFO_LOOP_NEST. * tree-vect-slp.c (destroy_bb_vec_info): Call free_data_refs and free_dependence_relations. * tree-vectorizer.h (struct _loop_vec_info): Add a field loop_nest. (LOOP_VINFO_LOOP_NEST): New.
