A broadcast_table modification query consists of the the key, the new value, and the condition. When preparing it, we construct the query with a default new_value expression, and pass it to operation::prepare_for_broadcast_tables() to fill .new_value. Since we're removing expression's default constructor, this won't work. So instead nothing to a (renamed) operation::prepare_new_value_for_broadcast_tables(), and use the return value to fill the query.
