Looks good to me. 

Just for reference, I want to mention that the merge conflict in `library_call.cpp` is because [8151779: Some intrinsic flags could be replaced with one general flag](https://bugs.openjdk.java.net/browse/JDK-8151779) is missing in JDK 15, but it obviously doesn't make sense to downport that huge change as a dependency for this downport.

Thanks,
Volker
