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.

Sure fine with me unless Kees screams.
