RFR : PPC64 : Need support for VSR spills in ppc.ad

We have nightly tests for jdk/hs so it gets tested automatically to some extent. More tests will run when we integrate it into SAP JVM.
So I think you don't necessarily have to wait until GA.

Backport changes should be tested better than running a few tests for a couple of days. Maybe you have nightly tests for 8u where you can test the backport for some time? I think this would be ideal. Otherwise, I'm a little concerned about possibly required shared fixes which were not backported to 8u.

I can answer questions or write an additional review.

Best regards,
Martin
