Auto merge of #45524 - alexcrichton:improve-park-unpark, r=dtolnay
std: Optimize thread park/unpark implementation This is an adaptation of alexcrichton/futures-rs#597 for the standard library. The goal here is to avoid locking a mutex on the "fast path" for thread park/unpark where you're waking up a thread that isn't sleeping or otherwise trying to park a thread that's already been notified. Mutex performance varies quite a bit across platforms so this should provide a nice consistent speed boost for the fast path of these functions.
