      Description

      We need to check and implement the missing intrinsics for AArch64.
      Most intrinsics are handled by platform-independent code, but we need to implement at least CompareAndExchange.

      See JDK-8148146 for x86 C2 implementation.
      See JDK-8152753 for x86 C1 implementation.
      Run hotspot/test/compiler/unsafe/ and jdk/test/java/lang/invoke/VarHandles/ jtregs to verify functionality.
      See JDK-8080605 for benchmarks to sanity test VarHandles/unsafe performance.
