RFR (11u, XXL): Upstream/backport Shenandoah to JDK11u

[Aleksei Voitylov]

That would be awesome, thanks!

I also saw interpreter/interpreter.hpp and a couple of other unguarded
modifications. While not strictly proving anything, guarding more code
with #ifdefs might be an option to simplify verification. And further
reduce risks for platforms that won't support Shenandoah (or help
maintain compatibility for those who prefer to build without it).
