Detailed Description
In BuildWhileGroups, a register is created for each iteration argumenet of the while op.
These registers are then written to on the while op terminating yield operation alongside before executing the whileOp in the schedule, to set the initial values of the argument registers.

Create iteration argument registers. The iteration argument registers will be referenced:
- In the "before" part of the while loop, calculating the conditional,
- In the "after" part of the while loop,
- Outside the while loop, rewriting the while loop return values.
Also replace uses in the "before" region of the while loop
Create iter args initial value assignment group(s), one per register.
Add the while op to the list of scheduleable things in the current block.
