The `tf_executor.island` region allows implicit capture. If any value captured
by a `tf_executor.island` is dead, the whole region does not execute and every
produced value is marked as dead as well.

An arbitrary number of `tf_executor.control` operands are accepted by a
`tf_executor.island` operation. If any operand is dead, the region is not
executed and dead values are immediately returned for every result.
