Auto merge of #2641 - DrMeepster:init_once_acquire, r=RalfJung
InitOnce: synchronize with completion when already complete The completion of an InitOnce happens-before the threads waiting on it wake up. However, this is not the case for threads that call `InitOnceBeginInitialize` after the completion, leading to data races and outdated weak memory loads as observed in the CI for #2638. This PR fixes this.
