That's easy enough:

int main() {
   int i;
   (void)(0 && i);
   return 0;
}

produces no warning about I being unused.  In theory any half way  
decent dead code stripper can rip out all the code as well, but, it  
does have to be valid code.  We'd just need a clang assert that does  
the right thing.
