[Bug libstdc++/38466] std::swap does not use std::swap for the components of a std::pair

The __swap_impl idea makes sense but note that user code can tell it from the
"standard" one when something throws. All in all, given that C++0x will be Ok
wrt these issues, I'm not sure we want to attempt something in C++03 mode. By
the way, as far as our specific implementation of std::string is concerned,
typically I would not expect a huge performance improvement, thanks to
copy-on-write. Do you have some numbers?
