Replace usage of Random

We need some randomness, but it doesn't need to be particularly good, just fast.  A simple xorshift prng is 3-4x faster than Random, in particular without multiple virtual method calls that don't get inlined.  It's also a bit lighter in terms of memory (though there's only one of these per thread, so it doesn't impact much).
