I am certainly not an expert in such things, but I don't see anything about the license that would make it non-free.
Yeah, this looks BSD-ish, plus a patent license. I suggest to add it to @MISC-FREE. Also Debian have this in free: https://packages.debian.org/source/stretch/llvm-toolchain-3.9 (see "Copyright File" there). CCing maintainers.
