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.
