LLVM 3.9 has some useful features, including support for the [[nodiscard]] 
attribute (https://clang.llvm.org/cxx_status.html) and support for GCC ABI tags 
(http://releases.llvm.org/3.9.0/docs/ReleaseNotes.html#gcc-abi-tag), which is 
required to support building against code generated by GCC 5 and later with the 
C++11 ABI.
