The worker clause specifies iterations of the loop/ that are executed in parallel by distributing the iterations among the multiple works within a single gang. The sema rules for this type are simply that it cannot be combined with a `kernel` construct with a `num_workers` clause, child `loop` clauses cannot contain a `gang` or `worker` clause, and that the argument is oly allowed when associated with a `kernel`.
