Kuba Mracek e4c1dd2c08 [tsan] Enable ignore_noninstrumented_modules=1 on Darwin by default
TSan recently got the "ignore_noninstrumented_modules" flag, which disables tracking of read and writes that come from noninstrumented modules (via interceptors). This is a way of suppressing false positives coming from system libraries and other noninstrumented code. This patch turns this on by default on Darwin, where it's supposed to replace the previous solution, "ignore_interceptors_accesses", which disables tracking in *all* interceptors. The new approach should re-enable TSan's ability to find races via interceptors on Darwin.

Kuba Brecka aafb41ae47 [tsan] Fix Darwin tests (missing FileCheck's)
A little embarrassing, but we're missing the call to FileCheck in several Darwin tests. Let's fix this.

Kuba Brecka 428a9f95a4 [asan,tsan] Make Darwin-specific tests more stable (use ignore_interceptors_accesses=1 for GCD tests and printf instead of NSLog).

Kuba Brecka 8f9607a616 [tsan] Add release+acquire semantics for serial dispatch queues
Serial queues need extra happens-before between individual tasks executed in the same queue. This patch adds `Acquire(queue)` before the executed task and `Release(queue)` just after it (for serial queues only). Added a test case.
