mjit_compile.c: drop catch table handling

Browse source 
The loop for `vm_exce_handle_exception` doesn't trigger `mjit_exec`, so
I don't think this code is no longer needed.

This was needed in development of original version of this JIT, but it
seems not needed from the beginning (r62189) at Ruby repository.
