[PATCH] D42411: [test-suite] Fix ambigous call to overloaded function isnan

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added a comment.

I guess a more C++y solution would be to `#include <cmath>` and using std::isnan() instead of using the C headers. But I guess this is fine for now.
