libstdc++: Implement C++23 std::bind_back from P2387R3 [PR108827]
The implementation is based off of std::bind_front. Since this is a C++23 feature we use deducing this unconditionally. PR libstdc++/108827 PR libstdc++/111327 libstdc++-v3/ChangeLog: * include/bits/version.def (bind_back): Define. * include/bits/version.h: Regenerate. * include/std/functional (_Bind_back): Define for C++23. (bind_back): Likewise. * testsuite/20_util/function_objects/bind_back/1.cc: New test (adapted from corresponding bind_front test). * testsuite/20_util/function_objects/bind_back/111327.cc: Likewise.
