[jdk17u-dev] RFR: 8307352: AARCH64: Improve itable_stub

[Dmitry Chuyko]

Original patch applies almost cleanly except few substitutions similar to https://github.com/openjdk/jdk17u-dev/pull/2654 and a single assert->guarantee change in assembler_aarch64.hpp that needed a trivial adjustment (JDK-8297830 is not in 17).

InterfaceCalls benchmark shows improvements similar to original results on linux aarch64.

Testing: linux aarch64 tier1,2.
