Failing test case for sorting NaN values.
Better test case to demonstrate NaN sorting issue.

This also applies to undefined values, which is where I first noticed it

implementation is unstable, so my previous attempt at an appropriate
test case didn't correctly detect the issue.
Fix sorting of undefined and NaN.

Unfortunately, this slows things down a bit due to the additional pass,
but perhaps it can be optimised later.
