arm64: Implement VarHandle CAS intrinsics.
And refactor Unsafe CAS intrinsics for code reuse.
Add extra tests to the 160-read-barrier-stress to test the
slow paths. The main path is sufficiently exercised by the
712-varhandle-invocations test. The refactored Unsafe CAS is
already covered by 004-Unsafe and 160-read-barrier-stress.
