Once we can't manipulate the address limit, we also can't test what happens when the manipulation is abused.
Just remove these tests entirely.
Once set_fs() doesn't exist on x86, the tests no longer make any sense
what-so-ever, because test coverage will be basically zero.
So don't make the code uglier just to maintain a fiction that
something is tested when it isn't really.
