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.

[CMake] Add the way to run tests in standalone build.
...
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.

[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.
