	instead of <functional>.
	* include/experimental/propagate_const: Include <bits/stl_function.h>,
	<bits/functional_hash.h>, and <bits/move.h> instead of <functional>.
	* include/experimental/tuple: Do not include <functional>.
	* include/std/future: Include <functional>.
	* include/std/memory: Do not include <functional>.
	* include/std/mutex: [_GLIBCXX_HAVE_TLS]: Likewise.
	* testsuite/20_util/shared_ptr/thread/default_weaktoshared.cc: Add
	missing includes.
