33155 also build a canonical type reference.
33156 (build_index_type): When we can't hash an index type (e.g.,
33157 because its maximum value is negative), the index type requires
33158 structural equality tests.
33159 (build_array_type): Build the canonical form of an array type.
33160 (build_function_type): Function types require structural equality,
33161 because they contain default arguments, attributes, etc.
