libstdc++: Reduce size of std::bind_front(F) result When there are no bound arguments to a std::bind_front call we don't need the overhead of compiling, initializing, and accessing an empty tuple. libstdc++-v3/ChangeLog: * include/std/functional (_Bind_front0): New class template. (_Bind_front_t): Use _Bind_front0 when there are no bound arguments. * testsuite/20_util/function_objects/bind_front/107784.cc: New test.
