Performance degradation in 1.10.1 after changing the behavior of `yield`

Describe the bug

In IntelliJ, we observe a performance degradation connected to #4255 . It seems that previously skipped tryUnpark starts to be visible in performance snapshots.

Provide a Reproducer

I did not build exact reproducer, but it likely involves a ton of yields; unfortunately, this sometimes happens in production. There is more information in https://youtrack.jetbrains.com/issue/IJPL-182130.
