12456 also build a canonical type reference.
12457 (build_index_type): When we can't hash an index type (e.g.,
12458 because its maximum value is negative), the index type requires
12459 structural equality tests.
12460 (build_array_type): Build the canonical form of an array type.

12462 because they contain default arguments, attributes, etc.
