libstdc++: Implement C++23 P1951R1 (Default Args for pair's Forwarding Ctor) [PR105505]
This was approved for C++23 at he June 2021 virtual meeting.
This allows more efficient construction of std::pair members when {} is
used as a constructor argument. The perfect forwarding constructor can
be used, so that the member variables are constructed from forwarded
arguments instead of being copy constructed from temporaries.
libstdc++-v3/ChangeLog:
PR libstdc++/105505
