<pre>Now that we moved libunwind to its own repository, and have made it compile and
run on buildbots around, we need to make sure we get all dependencies correct:
1. No hard-coded dependencies on any other component. Most relevant are
compiler-rt and libc++abi.
2. No cyclic dependency between all three low-level libraries, with both
compiler-rt and libc++abi using libunwind and not each other.
3. Build systems / CMake files need to be aware of the existence, so libunwind
can be used inside LLVM (projects/libunwind) and be used directly by
compiler-rt/libc+abi in case CMake options allow for this.
4. Different systems will have different defaults. For example, it's perfectly
valid for GNU systems to rely on libgcc / libgcc_s by default and BSD systems
to rely on compiler-rt / libunwind. There should be CMake settings for either
to change their behaviour.
5. All tests must pass in the targets they were passing before, namely
x86_64/ARM on linux/darwin.</pre>
