Generates a latency-insensitive FSM to realize a sequential operation.

This is done by initializing GroupGoOp values for the enabled groups in the SeqOp, and then creating a new Seq GroupOp with the given FSM. Each step in the FSM is guarded by the done operation of the group currently being executed. After the group is complete, the FSM is incremented. This SeqOp is then replaced in the control with an Enable statement referring to the new Seq GroupOp.
