23a5e91858 gowin: Add constraints on primitive placement. 
Added support for the INS_LOC instruction in the constraints file
(.CST), which is used to specify object placement.
Expanded treatment of IO_LOC/IO_PORT constraints, which now can
be applied to both ports and IO buffers.
Port constraints have priority.

e4196f32d3 gowin: Add the IO[TRBL]style placement recognition 
Specifying pin placement with this notation (e.g. IOR4B) allows
to use the same constraint file without changes for different
packages and even different families.
The vendor router also understands this notation.

e6006805ce Make EXTREFB handling more robust 
Avoids a segfault if an EXTREFB does not connect directly to its associated DCUA.
Also adds location constraints specifically for EXTREFB.
