This 'Icelake-Client' actually doesn't exist. How do we define its
feature list? and who will be using it? If any special feature tailor
requirement, it can be simply achieved by '-cpu Icelake,+/-' features,
this is the correct way.
I think we should remove it. When we realize something's not correct,
we should fix it ASAP. Leaving it there will only cause more serious
issue in the future.
