    libstdc++: Have std::addressof use __builtin_addressof
    
    Rather than calling std::__addressof in std::addressof we can directly
    call __builtin_addressof to bypass 1 function call.
    
    libstdc++-v3/ChangeLog:
    
            * include/bits/move.h (std::addressof): Call __builtin_addressof.
