24113 also build a canonical type reference.
24114 (build_index_type): When we can't hash an index type (e.g.,
24115 because its maximum value is negative), the index type requires
24116 structural equality tests.
24117 (build_array_type): Build the canonical form of an array type.
24118 (build_function_type): Function types require structural equality,
24119 because they contain default arguments, attributes, etc.
