* thread.c (rb_threadptr_execute_interrupts): now INT2FIX(TAG_FATAL)
  can be popped from async_errinfo_queue.

* vm.c (rb_vm_make_jump_tag_but_local_jump): revert r38441.
  rb_vm_make_jump_tag_but_local_jump() shouldn't return exception
  in case of state == TAG_FATAL.

  Thread.exit should terminate current Thread.
