absl: requeue waiters as LIFO
Currently if a thread already blocked on a Mutex,
but then failed to acquire the Mutex, we queue it in FIFO order again.
As the result unlucky threads can suffer bad latency
if they are requeued several times.
The least we can do for them is to queue in LIFO order after blocking.
