* 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 PBQP solver.
...
* Fixed a reduction bug which occasionally led to infinite-cost (invalid)
register allocation solutions despite the existence finite-cost solutions.
* Significantly reduced memory usage (>50% reduction).
* Simplified a lot of the solver code.

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.
