[Bug c++/19816] New: C++ front-end produces a cast instead of just &a.b (empty base class)

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

For the following code, the C++ front-end produces a case instead of doing &v.base which seems 
wrong in my mind.

struct base { base(); };
struct vector : public base { };
int f() { vector v; }


This might be the cause of PR 19786 but it might not (I have not looked at the aliasing sets for that bug 
yet).
