current test still doesn't fail. checkIndex just calls nextDoc() on
low-level vectors but we may need to invoke skipping to find the issue. That's
my theory at least.

Just as confirmation I'm seeing `FixedBitSet.clear` taking up a lot of time
as well when running this test.

With the 20M docs it still didnt fail. I have the index saved so i can play
around, maybe checkindex doesnt trigger what is needed here (e.g. advance vs
next).

@jdconrad helped with some math that may explain why previous tests didnt
fail:
```
jshell> int M = 16;
M ==> 16
jshell> long v1 = (1 + (M*2)) * 4 * 16268814;

Yes, if such a test works it may at least prevent similar regressions.
Another possible idea is to give every vector value of 0, then zip up the
index, it should be ~16MB of zeros w

@rmuir Thinking outside the box! I will try that. It would definitely cause
the graph offset calculation to be completely blown out of proportion! Which is
the cause of this overflow.
