http://gcc.gnu.org/PR44647 requests that std::new_handler  and
std::bad_alloc be put in separate files as this helps reduce code size
for embedded code linking to libstdc++.a.  I think the request is
reasonable so I plan to commit the attached patch to trunk unless I
hear objections.

        PR libstdc++/44647
        * libsupc++/Makefile.am (sources): Add bad_alloc.cc.
        * libsupc++/Makefile.in: Regenerate.
        * libsupc++/new_handler.cc (bad_alloc): Move to ...
        * libsupc++/bad_alloc.cc (bad_alloc): * New.

Tested x86_64/Linux
