Philipp Fent 93257ed603 libstdc++: Add pretty printer for std::stringstreams 
To display (o-,i-)stringstreams in the common case, we just print the
underlying stringbuf, without the many ios_base members. In the
unconventional case that the underlying streambuf was redirected, we
report the redirected target.

Signed-off-by: Philipp Fent <fent@in.tum.de>
