Add the test infrastructure for testing lib/profile and a single test.
This initial commit only enables the tests on Darwin, but they'll be
enabled on Linux soon after.

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.

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.

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.

1) Depend on llvm-config (configured in LLVM_CONFIG_PATH) to
get necessary LLVM source/binary directories.
2) Add basic support for running lit tests (check-xsan commands).
For now this "support" is far from what we want:
* unit tests are not built currently.
* lit tests use Clang/compiler-rt from LLVM build directory,
not the host compiler or just-built compiler-rt libraries.
We should make a choice on the way we intend ti run compiler-rt lit testsuite:
a) use either Clang from LLVM build tree, or the host compiler.
b) use either just-built runtimes, or the runtimes shipped with the
host compiler.
Using just-built runtimes is tricky - we have to know where to put them, so that
Clang/GCC driver would pick them up (and not overwrite the existing runtimes).
Using a host compiler instead of Clang from LLVM build tree will give us a chance to
run lit tests under GCC (which already has support for several sanitizers).
That is, I tend to make the following choice: if we're in a standalone compiler-rt
build, use host compiler with its set of runtime libraries to run lit tests.
This will effectively decouple "make compiler-rt" and "make check-compiler-rt" in
a standalone build - the latter wouldn't invoke the former. Note that if we decide
to fix LLVM/Clang/compiler-rt build system so that it would configure/build
compiler-rt with just-built Clang (as we do in Makefile-based build), this will not
be a problem - we can add a dependency to ensure that clang/compiler-rt are rebuilt
before running compiler-rt tests.

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.

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.

This change adds a copy of <ucontext.h> for Android found in google-breakpad
that is missing from the official NDK.
ASan SEGV handler is still disabled by default and can be enabled with
ASAN_OPTIONS=handle_segv.

If the -fno-function-sections flag isn't recognized, the compiler
emits a warning. This isn't enough to cause the check to fail, so we
enable -Werror as well.

It breaks when a binary is linked with --gc-sections: parts of sanitizer
interface get thrown away and inaccessible from dlopen-ed libs.
