Yes. It's definitely possible:

1.  Create new project.
2. Setup build infrastructure. Based on autotools/scons/cmake because
it should be cross-platform.
3. Setup installation.
4. Create packages for Debian/RedHat/YouNameIt because it's independent project.
5. Use it in Parrot for build LLVM JIT.

Comparing to:
1. Revert few commits.
2. Implement LLVM JIT.

Sorry, it's way too complex from my point of view.

OTOH, I don't mind to pass our "LLVM C API extensions" back to
upstream. However Python's LLVM binding author didn't receive any
response from LLVM for his request (which is quite similar to what I
want to implement).
