Thank you very much for setting up an APT repository with LLVM trunk in it.
LDC's CI systems are now working with the binaries available from llvm.org,
but for LLVM trunk we depend on the APT repo.

Just to be sure. Are you caching these binaries or are you downloading
them for each CI run? As you know, we had serious load problems, so
pointing uncached CI systems on any of these links is probably not a
good idea. ;)

Yes, the llvm.org binaries are cached.
The APT repository download isn't, as I don't know how to do that (yet).
