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
}
```

Issue 8830: New check: Function argument evaluates to constant value
...
Add a check for function arguments that can be constant:
```cpp
extern void bar(int);
void f(int x) {
bar((x & 0x01) >> 7); // function 'bar' is always called with a '0'-argument
}
```
