Kostya Serebryany 458b4006b2 [asan,tsan] Add a new directory compiler-rt/lib/sanitizer_common 
which will contain code shared between asan and tsan run-times.

Naming is hard. If you can suggest a better name for the directory -- speak up.

Dmitry Vyukov 7fb7330469 asan/tsan: weak interceptors 
The idea isthat asan/tsan can survive if user intercepts the same functions. At the same time user has an ability to call back into asan/tsan runtime. See the following tests for examples:
asan/output_tests/interception_failure_test-linux.cc
asan/output_tests/interception_test-linux.cc
asan/output_tests/interception_malloc_test-linux.cc

Dmitry Vyukov 19b855fe3e tsan: remove shutdown code 
tsan runtime shutdown is problematic for 2 reasons:
