Fix issue 8785: ValueFlow: Track pointer alias
...
This fixes the issue by making `ProgramMemory` keep track of values based on the conditions.
It also removes the `deadpointer` check since it duplicates the `invalidLifetime` check.

Fix FP: Unitialized variable when using a pointer
...
This fixes the FP in cases like this:
```cpp
void f() {
bool b;
bool * x = &b;
if (x != nullptr)
x = 1;
}
```
It tracks the indirection of the uninit value in valueflow.

Remove whole program analysis from 'uninitialized variables' and 'null pointer dereference' checkers. I think this logic can more or less be added in ValueFlow instead and then all ValueFlow checkers should get whole program analysis.
