[11u] RFR: 8244164: AArch64: jaotc generates incorrect code for compressed OOPs with non-zero heap base

[Nick Gasson]

Hi,

Could someone sponsor an 11u backport for me please?

Original:
  Bug: https://bugs.openjdk.java.net/browse/JDK-8244164
  Patch: https://hg.openjdk.java.net/jdk/jdk/rev/4cd328cdd20f

Applies cleanly on 11u except for a copyright header conflict in
AArch64HotSpotMove.java. I don't need to make a webrev for this, right?

Tested hotspot/jtreg/compiler/aot/* on AArch64.
