Sigmap single port bits in mux tree feedback search.
...
find_muxtree_feedback_patterns sigmapped the whole A/B/S ports of every
visited $pmux, which is O(port width) per visited bit and makes wide mux
trees quadratic. Sigmap only the single bit that is needed, via a new
port_bit() helper, and factor the repeated Sx port writes into
break_feedback(). Output is unchanged.
