This PR differs from the original change because some interpreter changes belonging to [JDK-8301993](https://bugs.openjdk.org/browse/JDK-8301993) are not in jdk21u. Fortunately, the inserted memory barriers can be mapped 1:1.

Hi @TheRealMDoerr 
this is brand new, and the aarch change referenced is not yet backported, either.  Should we really proceed? Or rather await the April update?
