Optimization: Removed unnecessary calls to simplifyPath(). The Caller should do this, and our callers (mainly the test suite) more or less do so, as they all supply just dummy paths ("test.cpp")

Fix issue 8829: Condition '...' is always true (int buf[42]; if(buf != NULL){})
...
This makes arrays non-null in valueflow, so it can catch comparisons against null that is always true:
```cpp
void f(void) {
int buf[42];
if( buf != 0) {;} // << always true
}
```

}
