LuaJIT already uses the native exception mechanism (i.e. C++
exceptions) to do the unwinding on x64. But that crashes if
there's an intervening JIT-compiled frame.
Longjmp might work, but then the LuaJIT VM is no longer in a sane
state. The only option would be to print some error and exit the
process (without touching the VM anymore).
