[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.

[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.

Revert "Replace __FUNCTION__ with __func__, the latter being standard C99/C++11."
...
This reverts commit r201910.
While __func__ may be standard in C++11, it was only recently added to
MSVC in 2013 CTP, and LLVM supports MSVC 2012. __FUNCTION__ may not be
standard, but it's *very* portable.

[asan] Do all calls to __asan_report_* through PLT.
...
This matters when runtime is built as a shared library. Even though calling
code is itself part of the same library, these symbols are public and can
(theoretically) be interposed.
It might be better to declare hidden aliases for asan_report_* and call them
directly, but
(a) they are (noreturn), so performance does not matter, and
(b) it may be potentially less portable.

[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.

[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.

[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.
