whitequark f24fb4ae82 cxxrtl: detect buffered comb wires, not just feedback wires.
Any buffered combinatorial wires (including, as a subset, feedback
wires) will prevent the design from always converging in one delta
cycle. Before this commit, only feedback wires were detected. After
this commit, any buffered combinatorial wires, including feedback
wires, are detected.
