27806 also build a canonical type reference.
27807 (build_index_type): When we can't hash an index type (e.g.,
27808 because its maximum value is negative), the index type requires
27809 structural equality tests.
27810 (build_array_type): Build the canonical form of an array type.
27811 (build_function_type): Function types require structural equality,
27812 because they contain default arguments, attributes, etc.
