Review Comment:
This trick seems work:
```
boolean level0IsDense =
encoding == DeltaEncoding.UNARY
&& docBitSet.getBits()[0] == -1L
&& docBitSet.getBits()[1] == -1L;
if (level0IsDense) {
assert Long.bitCount(docBitSet.getBits()[0]) +
Long.bitCount(docBitSet.getBits()[1])
== BLOCK_SIZE : "We are assuming BLOCK_SIZE == 128 here.";
...
}
```
