Kuba Brecka 419ebb2891 [tsan] Support C++11 call_once in TSan on Darwin
This patch adds a wrapper for call_once, which uses an already-compiled helper __call_once with an atomic release which is invisible to TSan. To avoid false positives, the interceptor performs an explicit atomic release in the callback wrapper.
