This looks good to me, although I'm wondering how much randomness do we really
need -- those BigIntegers are worrying. I think this can be improved later if
somebody wishes to dive into it.

> It would be helpful in TestPackedInts at least, in order to generate random
> values (as a workaround, we currently generate a random int between 0 and
> {{min(Integer.MAX_VALUE, PackedInts.maxValue(bitsPerValue)}}). Moreover, it
> would help to fix {{nextInt}} for large ranges (calling {{nextInt(random,
> -10, Integer.MAX_VALUE)}} or even {{nextInt(random, 0, Integer.MAX_VALUE)}}
> currently fails because the range of values is {{> Integer.MAX_VALUE}}.
