When I was first looking at LLVM, I googled a lot, and found somebody
saying to do it this way:

http://onesadcookie.com/trac/browser/AbandonedExperiments/Argh/CodeGen.g
(lines 43-51).  I'm pretty sure now though that that's the wrong way
to do it, that you can just add an existing C function to LLVM's
function table and it'll get called automatically.  There was somebody
talking about this on this list recently...
