12861 also build a canonical type reference.
12862 (build_index_type): When we can't hash an index type (e.g.,
12863 because its maximum value is negative), the index type requires
12864 structural equality tests.
12865 (build_array_type): Build the canonical form of an array type.
12866 (build_function_type): Function types require structural equality,
12867 because they contain default arguments, attributes, etc.
