The OS X symbolizers (namely AtosSymbolizer) don't return full file paths, only file names. This patch modifies `mutexset*.cc` tests not to require a path to be present in the symbol on the stack trace.

Even sleep(1) lead to episodical flakes on some machines.
Use an invisible by tsan barrier to enforce required execution order instead.
This makes the tests deterministic and faster.

Add a script that is used to deflake inherently flaky tsan tests.
It is invoked from lit tests as:
%deflake %run %t
The script runs the target program up to 10 times,
until it produces a tsan warning.
