> After LUCENE-3505, I want to do a slight cleanup:
> * compute the term conjunctions optimization in scorer(), so its applied even if we have optional and prohibited clauses that dont exist in the segment (e.g. return null)
> * use the term conjunctions optimization when optional.size() == minShouldMatch, as that means they are all mandatory, too.
> * don't return booleanscorer1 when optional.size() == minShouldMatch, because it means we have required clauses and in general BS2 should do a much better job (e.g. use advance).
