    libstdc++: [_Hashtable] Use std::addressof in post-C++11 code
    
    There is no need to use std::__addressof in post-C++11 code.
    
    libstdc++-v3/ChangeLog:
    
            * include/bits/hashtable.h: Replace usages of std::__addressof with
            std::addressof.
            * include/bits/hashtable_policy.h: Likewise.
