Dmitry Vyukov 6cfab724ec tsan: refactor deadlock detector 
Introduce DDetector interface between the tool and the DD itself.
It will help to experiment with other DD implementation,
as well as reuse DD in other tools.

Kostya Serebryany 796f6557bf [asan] *experimental* implementation of invalid-pointer-pair detector (finds when two unrelated pointers are compared or subtracted). This implementation has both false positives and false negatives and is not tuned for performance. A bug report for a proper implementation will follow.

Evgeniy Stepanov a16f327c27 [sanitizer] Sizes and layouts for sanitizers on FreeBSD. 
Patch by Viktor Kutuzov.

Evgeniy Stepanov 322e89c4e2 [asan] Install asan_device_setup to bin/ when targetting Android. 
asan_device_setup is a utility that prepares a device to run code built with
ASan. Essentially, it installs ASan runtime library into the system. For this
reason, it has to be at a predictable relative path from the runtime library
itself. We also plan to distribute this utility, packaged with runtime library
and maybe llvm-symbolizer, to the users.

Evgeniy Stepanov 6edfad4811 [asan] Don't disable SEGV handler on Android by default. 
This is done mostly for consistency, because this setting is normally overridden in cmake.

Reid Kleckner 0140ce483f Append -D__func__=__FUNCTION__ to SANITIZER_COMMON_CFLAGS 
This way it gets picked up for all sanitizer libs, both sanitizer_common
and asan.  I believe those are the only libs that build with asan.
There should be no need to set the __func__ definition inside
clang_compile.

Alexander Potapenko 4b1a7fe33a [ASan] Split interception-in-shared-lib-test.cc into two tests with platform-specific RUN commands.

NAKAMURA Takumi 9cd9ad6b9d [CMake] Introduce cmake_policy(CMP0022) for target_link_libraries(INTERFACE|PRIVATE). 
For now, use both keywords, INTERFACE and PRIVATE via the variable,
  - ${cmake_2_8_12_INTERFACE}
  - ${cmake_2_8_12_PRIVATE}

They could be cleaned up when we introduce 2.8.12.
