IEEE floating point is specified such that a comparison of NaN with itself returns false, and Python respects these semantics. This patch makes uPy also have these semantics. The fix has a minor impact on the speed of the object-equality fast-path, but that seems to be unavoidable and it's much more important to have correct behaviour (especially in this case where the wrong answer for nan==nan is silently returned).
