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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94514 91177308-0d34-0410-b5e6-96231b3b80d8
