[LLVMdev] Directly emit LLVM IR?

One more problem with this: in order to emit float constants you have  
to convert them to hexadecimal notation which I found nontrivial. My  
pet language is still lacking proper float support because of this.  
I'm not aware whether there are more pitfalls like this lurking  
around. (Time to finally move to the ocaml bindings.. :))

HTH,
Jan
