while loop body has a control barrier (`%barrier`) at the end which forces
a dependency and the two assign variable ops must wait for each other to
complete before starting the next iteration. Transforming these control
outputs to data outputs removes the dependency between the two assign
variable ops, thus allowing them to run in parallel across iterations.
