Ken-Patrick Lehrmann a114bf0293 Fix false positives with condition with || and &&
The value of something in the middle of a condition with mixed || and &&
gives no information on which branch will be taken.
For instance with:
```
int f(int a, int b, bool x) {\n"
  if (a == 1 && (!(b == 2 && x))) {
  } else {
    if (x) {
    }
  }

  return 0;
}
```
We can enter the if part whether x is true or false, and similarly,
enter the else part whether x is true or false. Same thing with the
value of b.

This fixes the following false positive with above code:
```
:4:13: style: Condition 'x' is always true [knownConditionTrueFalse]
        if (x) {
            ^
:2:33: note: Assuming that condition 'x' is not redundant
    if (a == 6 && (!(b == 21 && x))) {
                                ^

```
