28697 also build a canonical type reference.
28698 (build_index_type): When we can't hash an index type (e.g.,
28699 because its maximum value is negative), the index type requires
28700 structural equality tests.
28701 (build_array_type): Build the canonical form of an array type.
28702 (build_function_type): Function types require structural equality,
28703 because they contain default arguments, attributes, etc.
