55c9d43c70 interchange: Fix bug in site router where a bad solution isn't remove. 
This resulted in valid site routing solutions being missed.  Underlying
bug was an off-by-one error when unwinding a failed solution.

c8dccd3e7b Implement debugging tools for site router. 
- Finishes implementation of SiteArch::nameOfPip and SiteArch::nameOfWire
 - Adds "explain_bel_status", which should be an exhaustive diagnostic
   of the status of a BEL placement.
