    libstdc++: Tweak comments on includes in hashtable headers
    
    std::is_permutation is only used in <bits/hashtable.h> not in
    <bits/hashtable_policy.h>, so move the comment referring to it.
    
    libstdc++-v3/ChangeLog:
    
            * include/bits/hashtable.h: Add is_permutation to comment.
            * include/bits/hashtable_policy.h: Remove it from comment.
