104536b7aa interchange: add support for generating BEL clusters 
Clustering greatly helps the placer to identify and pack together
specific cells at the same site (e.g. LUT+FF), or cells that are chained through
dedicated interconnections (e.g. CARRY CHAINS)

fd93697a2d interchange: arch: do not allow site pips within sites 
During general routing, the only site pips that can be allowed are those
which connect a site wire to the routing interface.

This might be too restrictive when dealing with architectures that
require more than one site PIPs to route from a driver within a site to the routing
interface (which is something that should be allowed in the
interchange).
