1ea3fc8083 Allow SSIZE_T in addition to ssize_t (#2263) 
The Windows Data Type SSIZE_T is declared in BaseTsd.h
However, it is written in capital letters

- Fixes e.g. the following false positive:
  (portability) %zd in format string (no. 1) requires 'ssize_t' but the
  argument type is 'SSIZE_T {aka signed long long}'.

025881cf35 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
}
```
