Ok, I will check into it when things get stable.

Hmmm, forking llvm on github seems like the easiest. I had not looked at
the github llvm mirror before. That seems like a good way to keep it
everything in sync.

My quick read of the http://www.opensource.apple.com/apsl/ makes me
think compliance would be by documenting any modification from original,
keeping the license intact in source, and a prominent notice by
executable only versions of the license and how to view the modified
source. Not sure how that applies to a library.

That might be a good idea. Keeps licensing issues, if any, away from
druntime or LDC. As a separate lib, it can just be added to the link
command as needed. And easily removed if Apple turns tlv on for iPhone
