tangxifan 5d79a3f69f critical bug fixed when annotating the routing results.
Add previous node check. This is due to that some loops between SB/CBs may exist
when routing congestion is high, which leads to same nets appear in the inputs
of a routing multiplexer. Actually one of them is driven by the other as a downstream node
Using previous node check can identify which one to pick
