clang-tidy properly doesn't warn on
```
bool isnan(float a) {
return a != a;
}
```
however it does warn on the following:
```
$ cat /tmp/a.cc
template <typename T> bool isnan(T a) {
return a != a;
}
bool isnan2(float a) {
return isnan(a);
}
$ clang-tidy /tmp/a.cc --checks=misc-redundant-_expression_
1 warning generated.
/tmp/a.cc:2:12: warning: both sides of operator are equivalent [misc-redundant-_expression_]
2 | return a != a;
| ^
```
