Commit Message

Mike Crowe Sept. 28, 2019, 8:44 a.m. UTC 
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.
