Please review this webrev [1] which attempts to bring the AArch64::CPUFeature enum (Java) in sync with VM_Version::Feature_Flag enum (C++ enum) for aarch64.

This is in preparation for creating AArch64 some intrinsics  for Graal. But I found that the CPUFeature enum was not being transferred over to Graal for AArch64. In attempting to do that I then found out that CPUFeatures was not in sync with the VM_Version::Feature_Flag enum.

The bug report is filed at [2].

I am happy to modify the patch as necessary.
