On Android L, TSD destructors run 8 times instead of 4.
Back to 4 times on the current master branch (as well as on K).

pthread_getspecific is not async-signal-safe.
MsanThread pointer is now stored in a TLS variable, and the TSD slot
is used only for its destructor, and never from a signal handler.
This should fix intermittent CHECK failures in MsanTSDSet.

MSanDR is a dynamic instrumentation tool that can instrument the code
(prebuilt libraries and such) that could not be instrumented at compile time.
This code is unused (to the best of our knowledge) and unmaintained, and
starting to bit-rot.

This reduces .tbss from 109K down to almost nothing.
