Review comment:
We should propagate the global minimum score to the underlying scorer
(`Scorer#setMinCompetitiveScore`) too. The optimization above that compares
the current doc with the global minimum score is a good one but propagating the
global minimum score should be more effective since it will allow skipping hits
directly in the scorer.
