    libstdc++: use updated type for __unexpected_handler
    
    Commit f4130a3eb545ab1aaf3ecb44f3d06b43e3751e04 changed the type of
    __expected_handler in libsupc++/unwind-cxx.h to be a
    std::terminate_handler to avoid a deprecated warning. However, the
    definition in eh_unex_handler.cc still used the old type
    (std::unexpected_handler) and thus causes a warning when compiling
    libstdc++ with -Wdeprecated-declarations (which is the default, for
    example, for clang).
    
    Adapt the definition to match the declaration.
    
    libstdc++-v3/ChangeLog:
    
            * libsupc++/eh_unex_handler.cc: Adjust definition type to
            declaration.
