Log:
        * tree-vect-analyze.c (vect_analyze_data_ref_access): Don't fail on
        zero step in the outer-loop for loads.
        * tree-vect-transform.c (vect_create_data_ref_ptr): Takes additional
        argument (inv_p). Support zero step in the outer-loop.
        (vect_init_vector): Takes additional argument (bsi). Use it, if
        available, to insert the vector initialization.
        (get_initial_def_for_induction): Pass additional argument in call to
        vect_init_vector.
        (vect_get_vec_def_for_operand): Likewise.
        (vectorizable_store): Pass additional argument in call to
        vect_create_data_ref_ptr.
        (vect_setup_realignment): Likewise.
        (vectorizable_load): Likewise. Handle invariant load.
