LUCENE-10125: Speed up DirectWriter. (#327)
There was a regression introduced in
https://github.com/apache/lucene/pull/107/files#diff-49b11ced76acedf749c5a5a0ff6e7fe93b8fb64caf8697e487a56f4f7adbb510
where we moved from write logic that was optimized for every number of bits per
value to more general logic that had to work for every number of bits per value.
This PR doesn't restore as much specialization, but some middle ground that
makes flushes and merges of doc values noticeably faster (though not much
faster).

> There's been a significant drop in indexing throughput between 2021-04-12 and
> 2021-05-24 on the NYC Taxis benchmark. Unfortunately several suspects have
> been merged during that period of time so we might need to git bisect to
> figure out which one is responsible for the regression. Interestingly the
> sorted index looks less affected than the non-sorted indexes.
