25359 also build a canonical type reference.
25360 (build_index_type): When we can't hash an index type (e.g.,
25361 because its maximum value is negative), the index type requires
25362 structural equality tests.
25363 (build_array_type): Build the canonical form of an array type.
25364 (build_function_type): Function types require structural equality,
25365 because they contain default arguments, attributes, etc.
