I've fixed a bunch of bugs in deadlock detector just few hours ago.

Please re-test with these fixes:

http://llvm.org/viewvc/llvm-project/compiler-rt/trunk/lib/sanitizer_common/sanitizer_deadlock_detector.h?r1=224518&r2=224517&pathrev=224518
http://llvm.org/viewvc/llvm-project/compiler-rt/trunk/lib/sanitizer_common/sanitizer_deadlock_detector.h?r1=224519&r2=224518&pathrev=224519

I've also added a random stress test, and I think I saw your crash during
testing. It does not happen for me with the fixes.
