        * tree-vectorizer.c (free_stmt_vec_info): New function.
        (destroy_loop_vec_info): Move code to free_stmt_vec_info().
        Call free_stmt_vec_info(). Free LOOP_VINFO_STRIDED_STORES..
        * tree-vectorizer.h (free_stmt_vec_info): Declare.
        * tree-vect-transform.c (vectorizable_conversion): Free
        vec_oprnds0 if it was allocated.
        (vect_permute_store_chain): Remove unused VECs.
        (vectorizable_store): Free VECs that are allocated in the..
        function.
        (vect_transform_strided_load, vectorizable_load): Likewise.
        (vect_remove_stores): Simplify the code.
        (vect_transform_loop): Move code to vect_remove_stores().
        Call vect_remove_stores() and free_stmt_vec_info().
