16169 (build_reference_type_for_mode): When building a reference type,
16170 also build a canonical type reference.
16171 (build_index_type): When we can't hash an index type (e.g.,
16172 because its maximum value is negative), the index type requires
16173 structural equality tests.
16174 (build_array_type): Build the canonical form of an array type.
16175 (build_function_type): Function types require structural equality,
16176 because they contain default arguments, attributes, etc.
