31332 also build a canonical type reference.
31333 (build_index_type): When we can't hash an index type (e.g.,
31334 because its maximum value is negative), the index type requires
31335 structural equality tests.
31336 (build_array_type): Build the canonical form of an array type.
31337 (build_function_type): Function types require structural equality,
31338 because they contain default arguments, attributes, etc.
