d6fd0e7e5b common/placer1: In random pick, only use grid if there is more than 64 BELs 
If you have a large grid and very few BELs of a given type, picking a
random grid location yields very little odds of finding a BEL of that
type.

So for those, just put all of them at (0,0) and do a true random pick.
