[Martin Doerr]

> Clean backport of [JDK-8332920](https://bugs.openjdk.org/browse/JDK-8332920).
> Unfortunately, we're getting timeouts in the new test compiler/loopopts/TestPartialPeelAtUnsignedTestsNegativeLimit.java. Tier 1-4 have passed other than this one.
> Will retry later and possibly make adaptations.
