What would you even want the function to return in the first 
place? The CPU features you can use obviously depend on the 
specific CPU the executable will run on, so the answer can't 
generally by known at compile time.

Do you want to base your decision on the CPU of the build host? 
Or are you looking for an efficient way to implement the runtime 
check?
