libstdc++: Add testsuite proc for testing deprecated features

This change adds options to tests that explicitly use deprecated
features, so that -D_GLIBCXX_USE_DEPRECATED=0 can be used to run the
rest of the testsuite. The tests that explicitly/intentionally use
deprecated features will still be able to use them, but they can be
disabled for the majority of tests.

libstdc++-v3/ChangeLog:

	* testsuite/23_containers/forward_list/operations/3.cc:
	Use lambda instead of std::bind2nd.
