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.
