CPU feature detection in cpu/aarch64 assumes running on Linux. As a preparation for support of non-Linux AArch64 systems (i.e. windows-aarch64), Linux-specific code should go to os_cpu/linux_aarch64/vm_version_xxx.cpp.
There is also a chance to clean up a bit:
1. CPU features detection stub can be optimized
2. dcpop feature is parsed from /proc/cpuinfo, although it is also available in HWCAP vector.
3. AArch64 Feature_Flags implicitly mirrors of Linux HWCAP
