[J-core] j2 llvm repo?

I am the author of the j2 experimental llvm backend. Thank you for noticing my
work.

I started working on this as a student research project, and I actually
chose j2 as a target because it seemed to be resurrecting with the
j-core project.

I would say that the backend is **HIGHLY** experimental. I currently
work on it and I actually plan to make a pretty complete toolchain at the end,
by adding support to clang, llvm and lld.

So far, the backend supports basic branching, function calls, stack
management, but still lacks support for complex instructions generated
by LLVM. Basically, code generation is supported through all those
steps:

C    ->   IR  ->   .s            ->          .o -> executable ELF
  (clang)   (llvm)    (integrated assembler)   (lld)

It hasn't been tested that much and still remains an educational-purpose
backend.

Thank you for your interest,
