Optimize more cycles in DFG (#6173) 
Added a second algorithm to break cycles in DFG by identifying which
bits of a circular variable are actually independent of the variable,
then reuse the existing (but extended) driver tracing algorithm to
eliminate them.

This can fix up things like: `assign gray = binary ^ (gray >> 1)`

Break some combinational cycles in DFG (#6168) 
Added an algorithm that can break some combinational cycles in DFG, by
attempting to trace driver logic until we escape the cycle. This can
eliminate a decent portion of UNOPTFLAT warnings. E.g. due to this code:

```systemverilog
assign a[0] = .....;
assign a[1] = ~a[0];
```
