PR tree-optimization/47002
* tree-data-ref.c (compute_data_dependences_for_loop): Pass in a
pointer to the loop_nest.
(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.
