Cool, you're making great progress.

If LLI is your goal, there are two possibilities: you can either compile 
the runtime library to .bc file which you statically llvm-link in, or you 
can compile it to a .so file, which you ask lli to load, like this:

$ lli -load myruntimelib.so  myprogram.bc <args>
