Detailed Description
Builds a control schedule by traversing the CFG of the function and associating this with the previously created groups.
For simplicity, the generated control flow is expanded for all possible paths in the input DAG. This elaborated control flow is later reduced in the runControlFlowSimplification passes.

TODO(mortbopet): we could choose to support ie. std.switch, but it would probably be easier to just require it to be lowered beforehand.
Wrap each branch inside an if/else.
Schedule sequentially within the current parent control block.

Insert while iter arg initialization group(s). Emit a parallel group to assign one or more registers all at once.
Insert the while op itself.
If a bound was specified, add it.

Schedules a block by inserting a branch argument assignment block (if any) before recursing into the scheduling of the block innards.
Blocks 'from' and 'to' refer to blocks in the source program. parentCtrlBlock refers to the control block wherein control operations are to be inserted.
Schedule any registered block arguments to be executed before the body of the branch.
