Evgeniy Stepanov 856b11199f [asan] Fix SanitizerCommon.PthreadDestructorIterations test on Android L. 
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).

Evgeniy Stepanov 372deb091e [msan] Stop calling pthread_getspecific in signal handlers. 
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.

Evgeniy Stepanov 7555f5ed1f [msan] Remove MSanDR and supporting code. 
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.

Evgeniy Stepanov 7ad0bde843 [msan] Fix false positive on dynamic tls. 
Use existing DTLS code in sanitizer_tls_get_addr.{h,cc} to unpoison DTLS
blocks both on allocation and deallocation.

Evgeniy Stepanov f653cda269 [msan] Introduce MsanThread. Move thread-local allocator cache out of TLS. 
This reduces .tbss from 109K down to almost nothing.
