bitset.
Affects classic faceting enum method, JSON Facets enum method,
UnInvertedField faceting, GraphTermsQParser, JoinQParser.
Renamed SolrIndexSearcher.getLiveDocs to getLiveDocSet.

> SlowAtomicReader is of course slow, and it's getLiveDocs (based on MultiBits)
> is slow as it uses a binary search for each lookup. There are various places
> in Solr that use SolrIndexSearcher.getSlowAtomicReader and then get the
> liveDocs. Most of these places ought to work with SolrIndexSearcher's
> getLiveDocs method.
