22916 also build a canonical type reference.
22917 (build_index_type): When we can't hash an index type (e.g.,
22918 because its maximum value is negative), the index type requires
22919 structural equality tests.
22920 (build_array_type): Build the canonical form of an array type.
22921 (build_function_type): Function types require structural equality,
22922 because they contain default arguments, attributes, etc.
