* Updated the cost matrix normalization proceedure to better handle infinite costs.
...
* Enabled R1/R2 application for nodes with infinite spill costs in the Briggs heuristic (made
safe by the changes to the normalization proceedure).
* Removed a redundant header.

New C++ PBQP solver. Currently about as fast (read _slow_) as the old C based solver, but I'll be working to improve that. The PBQP allocator has been updated to use the new solver.
