Keep track of how many times a live range has been dequeued, and prioritize new ranges. When a large live range is evicted, it will usually be split when it comes around again. By deferring evicted live ranges, the splitting happens at a time when the interference pattern is more realistic. This prevents repeated splitting and evictions. llvm-svn: 126282
