While annotating `<complex>` with `[[nodiscard]]` I stumbled upon that annotating the overloads bellow with `[[nodiscard]]` does not produce the expected diagnostic in Clang 22 but it does in GCC 15. See: https://github.com/llvm/llvm-project/actions/runs/20003026692

```C++
c* d; // NOT OK
c* T(1); // expected-warning 3 {{ignoring return value of function declared with 'nodiscard' attribute}}
T(1) * c; // expected-warning 3 {{ignoring return value of function declared with 'nodiscard' attribute}}
c / d; // NOT OK
c / T(1); // expected-warning 3 {{ignoring return value of function declared with 'nodiscard' attribute}}
T(1) / c; // expected-warning 3 {{ignoring return value of function declared with 'nodiscard' attribute}}
```
