10353 also build a canonical type reference.
10354 (build_index_type): When we can't hash an index type (e.g.,
10355 because its maximum value is negative), the index type requires
10356 structural equality tests.
10357 (build_array_type): Build the canonical form of an array type.
10358 (build_function_type): Function types require structural equality,
10359 because they contain default arguments, attributes, etc.
10360 (build_method_type_directly): Ditto for method types.
