tsan: fix trace tests on darwin
The trace tests crashed on darwin because of some thread
initialization issues (thread initialization is somewhat
different on darwin).
Instead of starting real threads, create a new ThreadState
in the main thread. This makes the tests more unit-testy
and hopefully won't crash on darwin (there is almost no
platform-specific code involved now).
This will also help with future trace tests that will need
more than 1 thread. Creating more than 1 real thread and
dispatching test actions across multiple threads in the
required deterministic order is painful.
Depends on D110539.

tsan: make mem profile data more consistent
We currently query number of threads before reading /proc/self/smaps.
But reading /proc/self/smaps can take lots of time for huge processes
and it's retries several times with different buffer sizes.
Overall it can take tens of seconds. This can make number of threads
significantly inconsistent with the rest of the stats.
So query it after reading /proc/self/smaps.
