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 vecto
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.

https://lab.llvm.org/buildbot#builders/179/builds/1761
This is a latent bug in aarch64 virtual address space layout,
there is not enough address space to fit traces for all threads.
But since the trace space is going away with the new tsan runtime
(D112603), disable the test.

tsan: speed up pthread_setname_np
pthread_setname_np does linear search over all thread descriptors
to map pthread_t to the thread descriptor. This has O(N^2) complexity
and becomes much worse in the new tsan runtime that keeps all ever
existed threads in the thread registry.
Replace linear search with direct access if pthread_setname_np
is called for the current thread (a very common case).
