Erik Eckstein 1f3bff3f77 IRGen: fix failing unconditional class casts ...

When unconditionally casting from a base to a final derived class, e.g. `base as! Derived`, the program did not abort with a trap.
Instead the resulting null-pointer caused a crash later in the program.
This fix inserts a trap condition for the failing case of such a cast.
