24921 also build a canonical type reference.
24922 (build_index_type): When we can't hash an index type (e.g.,
24923 because its maximum value is negative), the index type requires
24924 structural equality tests.
24925 (build_array_type): Build the canonical form of an array type.

24927 because they contain default arguments, attributes, etc.
