34398 also build a canonical type reference.
34399 (build_index_type): When we can't hash an index type (e.g.,
34400 because its maximum value is negative), the index type requires
34401 structural equality tests.
34402 (build_array_type): Build the canonical form of an array type.
34403 (build_function_type): Function types require structural equality,
34404 because they contain default arguments, attributes, etc.
