Title: fix QA code for fast_atan2f to explicitly use std::isnan

subject says it all ... this QA code won't compile for me (on OSX, but I think this must be the case in general) because "isnan" is not defined in the current namespace. Using "std::isnan" does the trick, and should not hurt any other OS / compiler compilation since it is just making the namespace explicit instead of implicit. - MLD
