removed unnecessary Settings parameter from Check::runChecks() and made Tokenizer a reference (#5308) 
There was no need for the `Tokenizer` parameter to be a pointer as it
could never be `nullptr` and was also dereferenced without checking
first.

As a reference to the `Settings` was already available via the
`Tokenizer` there was no need to pass it separately. In the production
code there will only be one instance of it but in the tests we could
have accidentally passed a different one.

f75c15af56 Fix issue 6821: New check: access heap/stack data using address of variable 
This fixes errors with:

```cpp
int f() {
    int i;
    return (&i)[1];
}
```

It uses the lifetime analysis to detect the issues.

729f57d8f1 Start a major rewrite of CheckBufferOverrun. For now only the 'array index' and 'buffer overflow' checks are rewritten. 
There are important TODOs still; for instance adding CTU support using our CTU infrastructure, add handling of pointers (maybe I'll use FwdAnalysis for this), add handling of multidimensional arrays, etc..
