Paul Pluzhnikov 1bca6eb8ea Remove unnecessary calls to labs() 
We've just traced a large memory increase to that patch (Google ref:
b/18069427).
It appears that labs() was there for a good reason.

Sorry about that :-(

For the curious:

  unsigned long u1 = ~0UL;
  unsigned long u2 = labs(u1);

  assert(u1 != u2);  // labs on unsigned *may* have an effect, despite
what Clang says.

Attached patch suppresses the Clang warning, while still keeping the
original behavior (which I believe to be correct).

Thanks,
