This is a variant of mainline issue [JDK-8269775](https://bugs.openjdk.java.net/browse/JDK-8269775). It only showed up now because it requires AVX-512 VLBW capable machines. This PR is cherry-picking the fixes for [JDK-8269580](https://bugs.openjdk.java.net/browse/JDK-8269580) and [JDK-8269775](https://bugs.openjdk.java.net/browse/JDK-8269775) and adjusts them to Valhalla specific changes.

Best regards,
