@petrhosek @ldionne 
would it be better detect libunwind in LLVM_ENABLE_RUNTIMES?

We have similar thing for lld in compiler-rt.
There are trade offs:
1. checking LLVM_ENABLE_RUNTIMES simplify out of the end user experience,
1. forcing default  ON simplifies cmake files and avoids unexpected use of system lib
