 The alldocspostlist for chert currently uses the termlist table to get the
 list of documents.  However, chert now stores the document length for
 every document in a single list in the termlist table, so this should be
 used instead.  Not only would this help in the target of making the
 termlist table optional, I believe it would also involve less IO, and
 should make pure ValueRange searches faster, since these make use of an
 alldocspostlist to identify document IDs which exist.
