    Example:

This one reports -Woverloaded-shift-op-parentheses:
```
#include <iostream>

int main() {
    int a = 5;
    std::cout << "Test" << a == 5 ? 1 : 0;
    return 0;
}
```
warning: overloaded operator << has higher precedence than comparison operator [-Woverloaded-shift-op-parentheses]

But this one not:
```
#include <iostream>

int main()
{
    int a = 5;
    std::cout << "Test" << a ? 1 : 0;
    return 0;
}
```

And this one:
```
#include <iostream>

int main()
{
    int a = 5;
    std::cout << "Test" << static_cast<bool>(a) ? 1 : 0;
    return 0;
}
```
reports: warning: operator '?:' has lower precedence than '<<'; '<<' will be evaluated first [-Wparentheses]

I would expect that all of above report some sort of warning.
This is reported by Sonar as CWE-783: https://cwe.mitre.org/data/definitions/783.html
"Suspicious calculation. Please use parentheses to clarify the code. The code ''a+b?c:d'' should be written as either ''(a+b)?c:d'' or ''a+(b?c:d)''."

This should be handled by some warning, or by some clang-tidy check.
