91856859d6 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.

c8b6926801 Added legal stuff, fixed some formatting issues. Removed the graph generator stuff as it was only meant for debugging the solver.

66ecec971d 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.
