  Log:
  Slightly move labels around to make sure we call ast() on our way out
  after a fork(2) in fork_trampoline(). By moving the epc_syscall_return
  label immediately before the call to do_ast() in epc_syscall(), we not
  only achieve that but also handle the detour through exception_return
  when the frame corresponds to an asynchronous kernel entry. Hence, we
  simplified fork_trampoline() as a side-effect.
