[aarch64-port-dev ] We Rock.

[White, Derek]

I think Dmitry has them just about all done. 1 went into JDK 10, the rest should make it into JDK 11. An Oracle presentation on Compact Strings for JDK 9 mentioned that Intel put 2 engineer years into intrinsics and tuning for Compact Strings on x86 in JDK 9!

So yah, we were a little behind.
