Adhemerval Zanella 7a096596b2 [compiler-rt] Remove SANITIZER_AARCH64_VMA usage
This patch complete removed SANITIZER_AARCH64_VMA definition and usage.
AArch64 ports now supports runtime VMA detection and instrumentation
for 39 and 42-bit VMA.

It also Rewrite print_address to take a variadic argument list
(the addresses to print) and adjust the tests which uses it to the new
signature.

Kuba Brecka 1a26ff7d17 [tsan] Fix deadlock_detector_stress_test.cc testcase for OS X
On OS X, we don't have pthread spinlocks, let's just use a regular mutex instead. Secondly, pthread_rwlock_t is much larger (200 bytes), so `char padding_[64 - sizeof(pthread_rwlock_t)]` actually underflows.

Kuba Brecka 153594694b [tsan] Implement "%env_tsan_opts" substitution to inherit default TSAN_OPTIONS
We already have %env_asan_opts for ASan, let's implement the same for TSan.

Dmitry Vyukov 57f2e64c06 tsan: fix parsing of second_deadlock_stack flag
It was broken during flag parsing refactoring.
Enable test for the flag.

Dmitry Vyukov 3ab6b2347e tsan: remove sleeps from tests
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.

Dmitry Vyukov 233f401c2b tsan: make positive tests more robust
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.
