If you're interested in producing transformed source code, you should really
use the rewriter (and tell us if that's insufficient for some reason).  If you're
interested in producing transformed machine code, you can either follow one
of Doug's suggestions or, if the code you want to emit is pretty straightforward,
you can alter the LLVM IR after CodeGen is done with it.
