[Clang] Force expressions with UO_Not to not be non-negative (#126846)
This PR addresses the bug of not throwing warnings for the following
code:
```c++
int test13(unsigned a, int *b) {
return a > ~(95 != *b); // expected-warning {{comparison of integers of different signs}}
}
```
However, in the original issue, a comment mentioned that negation,
pre-increment, and pre-decrement operators are also incorrect in this
case.
Fixes #18878
