tsan: allocate vector clocks using slab allocator
...
Vector clocks is the most actively allocated object in tsan runtime.
Current internal allocator is not scalable enough to handle allocation
of clocks in scalable way (too small caches). This changes transforms
clocks to 2-level array with 512-byte blocks. Since all blocks are of
the same size, it's possible to cache them more efficiently in per-thread caches.

[Sanitizer] Add generic ThreadRegistry class for sanitizer runtimes. This class holds basic thread bookkeeping logic and allows specific sanitizer runtimes to create thread contexts and mark threads as created/running/joined etc. The class is based on the way we currently store thread contexts in TSan.
