tsan: fix large stack frame in deadlock detector
...
In member function 'virtual void __sanitizer::DD::MutexBeforeLock(__sanitizer::DDCallback*, __sanitizer::DDMutex*, bool)':
error: the frame size of 544 bytes is larger than 512 bytes [-Werror=frame-larger-than=]
The code is now [arguably] better as well.

Introduce DDetector interface between the tool and the DD itself.
It will help to experiment with other DD implementation,
as well as reuse DD in other tools.
