[committed] libstdc++: Simplify nullary _Flat_set_impl::_M_try_emplace overload

[Tomasz Kamiński]

From: Patrick Palka <ppalka@redhat.com>

Remove the unused template parameter pack _Args (which always gets
deduced to an empty pack).

libstdc++-v3/ChangeLog:

	* include/std/flat_set (_Flat_set_impl::_M_try_emplace):
	Turn nullary overload into a non-template.
