> Clean backport of [JDK-8272315](https://bugs.openjdk.org/browse/JDK-8272315). It's only an enhancement, but it is required for other changes. E.g. the "Represent Registers as values" changes which were done for GCC 11 support like [JDK-8297445](https://bugs.openjdk.org/browse/JDK-8297445) don't build without it: `no known conversion for argument 1 from 'Register' to 'AbstractRegister' {aka 'AbstractRegisterImpl*'}`

GHA test failure is unrelated.
