    libstdc++: [_Hashtable] Insert range of types convertible to value_type PR
105717

    Fix insertion of range of instances convertible to value_type.

    libstdc++-v3/ChangeLog:

            PR libstdc++/105717
            * include/bits/hashtable_policy.h (_ConvertToValueType): New.
            * include/bits/hashtable.h (_Hashtable<>::_M_insert_unique_aux):
New.
            (_Hashtable<>::_M_insert(_Arg&&, const _NodeGenerator&,
true_type)): Use latters.
            (_Hashtable<>::_M_insert(_Arg&&, const _NodeGenerator&,
false_type)): Likewise.
            (_Hashtable(_InputIterator, _InputIterator, size_type, const
_Hash&, const _Equal&,
            const allocator_type&, true_type)): Use this.insert range.
            (_Hashtable(_InputIterator, _InputIterator, size_type, const
_Hash&, const _Equal&,
            const allocator_type&, false_type)): Use _M_insert.
            * testsuite/23_containers/unordered_map/cons/56112.cc: Check how
many times conversion
            is done.
