[Attributor][FIX] Do not simplify byval arguments

A byval argument is a different value in the caller and callee, we
cannot propagate the information as part of AAValueSimplify. Users that
want to deal with byval arguments need to specifically perform the
argument -> call site step. We do not do this for now.
