21738 also build a canonical type reference.
21739 (build_index_type): When we can't hash an index type (e.g.,
21740 because its maximum value is negative), the index type requires
21741 structural equality tests.
21742 (build_array_type): Build the canonical form of an array type.
21743 (build_function_type): Function types require structural equality,
21744 because they contain default arguments, attributes, etc.
