        * tree-vectorizer.c (vect_is_simple_use): Fix indentation.
        * tree-vect-transform.c (vect_get_constant_vectors): Use vectype
        instead of vector_type for constants. Take computation out of loop.
        (vect_get_vec_def_for_operand): Use only vectype for constant case,
        and use only vector_type for invariant case.
        (get_initial_def_for_reduction): Use vectype instead of vector_type.
