This change switches tsan to the new runtime which features:
- 2x smaller shadow memory (2x of app memory)
- faster fully vectorized race detection
- small fixed-size vector clocks (512b)
- fast vectorized vector clock operations
- unlimited number of alive threads/goroutimes
Depends on D112602.

Write uptime in real time seconds for every mem profile record.
Uptime is useful to make more sense out of the profile,
compare random lines, etc.
Depends on D110153.

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.
Depends on D110149.
