Dan Peebles f3aeb3b0ab llvm-39: a couple of improvements
Splits outputs in clang like we do in 3.8 and 4.0 to avoid runtime
dependency on Python in the main derivation.

I also disable TSAN on Darwin to maintain consistency with 4.0, which
disables it because it forces an unfree dependency in the stdenv.

# TSAN requires XPC on Darwin, which we have no public/free source files for. We can depend on the Apple frameworks
# to get it, but they're unfree. Since LLVM is rather central to the stdenv, we patch out TSAN support so that Hydra
# can build this. If we didn't do it, basically the entire nixpkgs on Darwin would have an unfree dependency and we'd
# get no binary cache for the entire platform. If you really find yourself wanting the TSAN, make this controllable by
# a flag and turn the flag off during the stdenv build. I realize that this LLVM isn't used in the stdenv but I want to
# keep it consistent with 4.0. We really shouldn't be copying and pasting all this code around...
