18775 also build a canonical type reference.
18776 (build_index_type): When we can't hash an index type (e.g.,
18777 because its maximum value is negative), the index type requires
18778 structural equality tests.
18779 (build_array_type): Build the canonical form of an array type.
18780 (build_function_type): Function types require structural equality,
18781 because they contain default arguments, attributes, etc.
