86699b42f6 Switch to potentially-sparse net users array 
This uses a new data structure for net.users that allows gaps, so
removing a port from a net is no longer an O(n) operation on the number
of users the net has.

22e4081c73 gowin: Add GUI. 
* Items such as LUT, DFF, MUX, ALU, IOB are displayed;
* Local wires, 1-2-4-8 wires are displayed;
* The clock spines, taps and branches are displayed with some caveats.

For now, you can not create a project in the GUI because of possible
conflict with another PR (about GW1NR-9C support), but you can specify
the board in the command line and load .JSON and .CST in the GUI.

Although ALUs are displayed, but the CIN and COUT wires are not. This is
still an unsolved problem.

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.
