re PR tree-optimization/29330 (-O -ftree-loop-linear --> virtual memory exhausted)
PR tree-optimization/29330
* tree-data-ref.c (free_data_ref): Use DR_FREE_ACCESS_FNS macro.
(initialize_data_dependence_relation): Clear DDR_LOOP_NEST pointer
on newly allocated ddrs.
(find_loop_nest_1, find_loop_nest): Change LOOP_NEST to a pointer
to VEC (loop_p, heap) pointer.
(compute_data_dependences_for_loop): Adjust caller.
(free_dependence_relations): Free DDR_LOOP_NEST.
* tree-loop-linear.c (linear_transform_loops): Don't forget to
free DEPENDENCE_RELATIONS and DATAREFS.
* gcc.dg/pr29330.c: New test.
