For one example, a year ago I had to make dmd work on Win64. LLVM didn't

The answer to that would be: contribute that implementation to LLVM. But I know
you're opposed to that as well.
If they don't accept the contributions, use a fork.
Easy to say, but doing Win64 was a major effort:
1. bizarre function calling conventions
2. undocumented symbolic debug info format
3. new object file format
Making such changes on a backend without thoroughly understanding how the
backend works would be quite a challenge. I seriously doubt anyone could have
done that on the tight schedule I was under.
Besides, forking LLVM subverts most of the advantages of using it.
