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

minor tweak on the scan-chain support in VPR8 as well as architecture file
...
Do NOT use pack patterns for the scan-chain. It will cause searching root chain in VPR8 to fail
Actually, we do not use scan-chain in mapping designs. Disable the pack pattern has no impact
