Don't reconstruct expression on encountering fatal error

Browse Source 
In some cases, like when given

```cpp
std::vector<char>* str =
reinterpret_cast<std::vector<char>*>(0x1234458);
CHECK(*str == std::vector<char>());
```

reconstructing the expression to report it would cause another fatal
error. Instead we just put together an AssertionResult without
reconstructing the expression fully.

This should fully fix #810
