Stop using Ref::map for style().

Browse source 
It's not possible to implement a Ref::map equivalent method on AtomicRefCell
while having AtomicRefCell implemented on top of RwArc. We could potentially
reimplement AtomicRefCell to be more like RefCell and add a Ref::map equivalent
method, but I (and pcwalton) think we should try just cloning a few extra
Arcs at these callsites instead.
