I think the test originated because of a bug where, even if the output
dtype was uint64, 32-bit integers wrapped.  We could therefore modify
the test to work on numbers closer to that upper limit; however, since
the current test doesn't evaluate elements but simply determines
whether they are in the 64-bit range, I think we're ok.
