5a76b3cb4d gowin: Add simplified IO cells processing 
Some models have I/O cells that are IOBUFs, and other types (IBUFs and
OBUFs) are obtained by feeding 1 or 0 to the OEN input.  This is done
with general-purpose routing so it's best to do it here to avoid
conflicts.

For this purpose, in the new bases, these special cells are of type IOBS
(IOB Simplified).

The proposed changes are compatible with bases of previous versions of
Apycula and do not require changing .CST constraint files.

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.
