Paul Fultz II 3975913637 Extend lifetime checking for references
This will use the lifetime checker for dangling references. It will find these cases for indirectly assigned reference:

```cpp
int &foo()
{
    int s = 0;
    int& x = s;
    return x;
}
```

This will also fix issue 510 as well:

```cpp
int &f( int k )
{
    static int &r = k;
    return r;
}
```

IOBYTE 184537884f Don't remove the volatile keyword so we can properly overload functions. (#1218)
* Don't remove the volatile keyword so we can properly overload functions.

I fixed all the checks that had tests that use volatile.  There will
probably be more changes needed due to lack of test coverage for
volatile in some checks.

* Fix unused private function warning.
