Yes. Correct.
NativeRegisterContextWindows_arm64 class now inherits from both NativeRegisterContextWindows and NativeRegisterContextDBReg_arm64 but both of these classes previously inherited from NativeRegisterContextRegisterInfo non-virtually. This caused multiple instances of NativeRegisterContextRegisterInfo in the hierarchy.
I have now changed NativeRegisterContextWindows definition to inherit NativeRegisterContextRegisterInfo virtually 
which shifts the responsibility of initializing NativeRegisterContextRegisterInfo to the most derived class.
Thats why this and other similar changes have been made.
