Easy to say, but doing Win64 was a major effort:

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.
Yes, I understand that. Hopefully you wouldn't have moved to LLVM and at
the same time implement Win64. Meaning that hopefully you would have had
better knowledge about the LLVM source code when starting with Win64.
Besides, forking LLVM subverts most of the advantages of using it.
Just fold in the changes from upstream. Yes, I know that won't be as
easy as having the code merged with upstream.
