Paul Fultz II 1afd56e964 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.

Paul Fultz II 1f747d0b14 Add regression test for 9281 (#2097) 2019-08-19 09:09:07 +02:00
Paul Fultz II ee7fe3aaa1 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.
