I ran into some pre-existing code that got broken by this change. Original version was 
```
std::vector<double> foo;
return std::find_if_not(std::begin(foo), std::end(foo), std::isnan<double>);
```

Now the templated version is gone, and std::isnan(double) seems to be have `int` return value, breaking the call above with "Candidate template ignored: couldn't infer template argument '_Predicate'".

Does this work as intended?
