59874188a6 generic: Refactor for faster performance 
This won't affect Python-built arches significantly; but will be useful
for the future 'viaduct' functionality where generic routing graphs can
be built on the C++ side; too.

ddb084e9a8 archapi: Use arbitrary rather than actual placement in predictDelay 
This makes predictDelay be based on an arbitrary belpin pair rather
than a arc of a net based on cell placement. This way 'what-if'
decisions can be evaluated without actually changing placement;
potentially useful for parallel placement.

A new helper predictArcDelay behaves like the old predictDelay to
minimise the impact on existing passes; only arches need be updated.

Fix chain swap

8c97cbe341 Fix chain swap 
Issue was due to dest_bels being not cleared between clusters unbindes, causing
newly bind bels to be unbinded and having their old bel value changed to new bel value.
Then when swap failed 2 cells were being bind to a single bel.

I tested leaving dest_bels in the function scope and moving it to the loop scope.
Code with dest_bels in the loop scope was faster than leaving it in the function scope,
and checking if the cell is in the processed cluster.
