Alexey Samsonov de4ef2a066 [CMake] Rudimentary support for standalone CompilerRT build system. 
This change allows to build compiler-rt libraries separately from
LLVM/Clang (path to LLVM build directory should be specified at
configure time). Running tests is not yet supported.

Evgeniy Stepanov aa9d74cc5d [asan] Android test runner for ASan lit tests. 
This change replaces 32- and 64- bit config.in-s with a single config template
that is used to generate both 32 and 64 bits configs as well as the new
arm-android config. Arm-android config is special because it can run tests on
a remote device over adb (android debug bridge). 

We replace %clang with a script that run the compiler, upload the result to
the device, and replaces it with another script. The second script runs the
binary on the device and delivers stdout/stderr/exitcode back.

Evgeniy Stepanov 391f0234eb [asan] Fix null_deref test with zero base shadow. 
With zero base shadow, shadow for near-zero access is itself at near-zero
location. As a result, this test crashes on the shadow access, and not on the
app access.

Relax a check to match this behavior.

Evgeniy Stepanov 788527d9cd Remove a check from strerror_r test.

Evgeniy Stepanov 769d46f373 [sanitizer] Use system unwinder in signal handlers on Android. 
Because of the way Bionic sets up signal stack frames, libc unwinder is unable
to step through it, resulting in broken SEGV stack traces.

Luckily, libcorkscrew.so on Android implements an unwinder that can start with
a signal context, thus sidestepping the issue.
