I'm not so sure. I know I wouldn't expect to get a different type back
with a call to abs(). Do we really want to change that expectation just
for the case of MIN_INT?
While everyone is going to want an unsigned value when calling abs(),
who knows if they might want to use negative numbers later? Like:
x = abs(x)
x *= -1
Now what do we get/want?
