     * include/bits/hashtable.h
     (_Hashtable<>_M_insert_multi_node(hash_code, node_type*)): New.
     (_Hashtable<>_M_insert(_Args&&, false_type)): Use latter.
     (_Hashtable<>::_M_emplace(false_type, _Args&&...)): Likewise.
     (_Hashtable<>::_M_insert_bucket): Replace by ...
     (_Hashtable<>::_M_insert_unique_node(size_type, hash_code, 
node_type*)):
     ... this, new.
     (_Hashtable<>::_M_insert(_Args&&, true_type)): Use latter.
     (_Hashtable<>::_M_emplace(true_type, _Args&&...)): Likewise.
     * include/bits/hashtable_policy.h (_Map_base<>::operator[]): Use
     latter, emplace the value_type rather than insert.
