19617 also build a canonical type reference.
19618 (build_index_type): When we can't hash an index type (e.g.,
19619 because its maximum value is negative), the index type requires
19620 structural equality tests.
19621 (build_array_type): Build the canonical form of an array type.
19622 (build_function_type): Function types require structural equality,
19623 because they contain default arguments, attributes, etc.
