Review Comment:
From what I can tell, `ScorerSupplier` is an optional interface, which is
probably just fine for most things (I am unsure which queries satisfy it or if
we care).
I am not 100% sure the expensive part we are trying to bypass. But in a
`BooleanQuery`, if we hit an "expensiveScorerSupplier" first, we will call
`scorerSupplier.cost()` on that "expensiveScorerSupplier". If this is fine &
still allows for the biggest optimizations (bypassing
`scorerSupplier.get(leadCost)`), then this solution is rather nice!
