10696 also build a canonical type reference.
10697 (build_index_type): When we can't hash an index type (e.g.,
10698 because its maximum value is negative), the index type requires
10699 structural equality tests.
10700 (build_array_type): Build the canonical form of an array type.

10702 because they contain default arguments, attributes, etc.
