Interesting! It seems the biggest difference is that the implementation here does not explicitly construct the DJ graph and uses BitVectors instead of sets. It would probably make sense to split up the mergeset part and the PromoteMem2Reg part once they are ready for committing. Let me know if you are interesting in trying the implementation for your patch, I'd be happy to split it up sooner.
