input (control and non-control) is dead, all the outputs (control and
non-control) are dead as well. For `tf_executor.Merge`, the output is dead only
when either an input control token is dead or all of the regular inputs are
dead. For `tf_executor.ControlTrigger`, a live control output is always produced
even when some control inputs are dead.

    An arbitrary number of `tf_executor.control` operands are accepted by a

    If any operand or implicitly captured value are dead, the region is not
    executed and dead values are immediately returned for every result.
