Gowin. Unbreak the segment routing. (#1508) 
Use loop enumeration of PIPs instead of direct name construction for the
upper and lower ends of the segment wire.

Also do not allow clock wires for segments.

Gowin. BUGFIX. Fix routing of the FF inputs. (#1498) 
A segment router replaces the source-to-sink connection by
general-purpose PIPs with bus-branch segment network connections.

The problem arises when the source is connected to the sinks directly
without switching as in the case of LUT->DFF, such wires should be left
as is, which is what this PR does.
