24798 also build a canonical type reference.
24799 (build_index_type): When we can't hash an index type (e.g.,
24800 because its maximum value is negative), the index type requires
24801 structural equality tests.
24802 (build_array_type): Build the canonical form of an array type.
24803 (build_function_type): Function types require structural equality,
24804 because they contain default arguments, attributes, etc.
