Dmitry Vyukov b332134921 tsan: new runtime (v3) 
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.

Dmitry Vyukov ed7f3f5bc9 tsan: move shadow stack into ThreadState 
Currently the shadow stack is located in the trace memory mapping.
The new tsan runtime will remove the trace memory mapping.
Move the shadow stack into ThreadState as a preparation step.
