Tim Edwards 4457248ecd Corrected a long-standing issue with permutation, which turned out
to be caused by failing to have a systematic way of determining
which pin's hash value would be used for the hash value of all the
pins.  Because equivalent cells in the two netlists may have pins in
different order, it was possible that they might end up with
different hashes.  This was solved simply by always taking the
larger hash value of the two pins belonging to the permutable pair.
Now permutation works correctly for arbitrary subcircuits.
(Previously it worked for low-level components like MOSFETs because
the pin order is always the same.)
