JIT can and will crash if program does too bad/stupid things.

Usually it seems to happen when branch/jump instructions (that was already translated) suddenly gets invalid target address when it runs translated code. It is not validated anymore after translation to keep it as fast as possible.

I am not going to touch JIT too much. I already had to fix some old shift instruction bugs and it is really annoying work and it still needs to be more optimal.
