re PR sanitizer/59410 (tsan tests fail with address randomization disabled)

	PR sanitizer/59410
	* lib/tsan-dg.exp (tsan_init): Instead of not running any
	tsan tests if trivial testcase doesn't run, set dg-do-what-default
	to compile.
	(tsan_finish): Restore dg-do-what-default.
	* g++.dg/tsan/atomic_free.C: Remove dg-do line.
