        (vect_mark_stmts_to_be_vectorized): The use corresponding to the
        reduction variable in a reduction stmt does not mark its defining phi
        as relevant. Update documentation accordingly.
        (vect_can_advance_ivs_p): Skip reduction phis.
        * tree-vect-transform.c (vect_get_vec_def_for_operand): Takes
        additional argument. Handle reduction.
        (vect_create_destination_var): Update call to vect_get_new_vect_var.
        Handle non-vector argument.
        (get_initial_def_for_reduction): New function.
        (vect_create_epilog_for_reduction): New function.
