[llvm-commits] Speeding up instruction selection

[Evan Cheng]

Please hold off checking it in for a bit. llvm tot is having some  
problems and I'd like to get to the bottom of it first.

Also, the tie breaker is less than ideal. I think we need a tie- 
breaker that is "the SUnit that's added to the queue is preferred".  
That means it prefers nodes which are closer to the end of block. What  
do you think?
