[PATCH v2 06/11] libstdc++ testsuite: Move slow_clock to its own header

[Mike Crowe <mac at mcrowe dot com>]

Move slow_clock test class into a header file so that it can be used by
other tests in the future.

	* testsuite/util/slow_clock.h: New file. Move implementation of
	slow_clock test class.

	* testsuite/30_threads/condition_variable/members/2.cc: Include
	slow_clock from header.
