34404 also build a canonical type reference.
34405 (build_index_type): When we can't hash an index type (e.g.,
34406 because its maximum value is negative), the index type requires
34407 structural equality tests.
34408 (build_array_type): Build the canonical form of an array type.
34409 (build_function_type): Function types require structural equality,
34410 because they contain default arguments, attributes, etc.
