Fix assertThat(Double.NaN).isNaN() in GWT/j2cl.

In Java there is a difference between:
  Double.NaN == Double.NaN ==> False
and:
  new Double(NaN).equals(Double.NaN) ==> true

For performance reasons double is devirtualized in GWT/j2cl and thus making that difference is much much harder. Eventually this will be resolved with b/36792681, but right now truth does not work.

This changes truths implementation do testing directly for NaN instead of relying on Object.equals for isNaN.
Probably truth should run its tests in GWT/J2CL to catch such errors.
