I think we also need an assertion function that behaves like np.allclose
-- the ULPs are somewhat unintuitive to work with, and an atol/rtol
combination also gets the job done, so some people might prefer that.
There's `assert_tol_equal` in scipy.special tests that could just be
copied to numpy.testing.
