You need to have the function declaration and insert a call to that. 
Once your LazyFunctionCreator is called, you fill in the body and call 
JIT->getPointerToFunction() on it and return that result.

I haven't actually tried this, but it seems to be the only way to use 
this API, so I presume someone else has. The only potential problem I 
can forsee is if the JIT isn't actually re-entrant.
