  Issue #1772851.  Alters long.__hash__ from being *almost* completely
  predictable to being completely predictable.  The value of hash(n)
  is unchanged for any n that's small enough to be representable as an
  int, and also unchanged for the vast majority of long integers n of
  reasonable size.
