Make sure we add body-less functions to our program as well, and add the actual body later. We then need to compile functions again later once we have the definition with a body.

We do  a bunch of work in `ByteCodeEmitter::compileFunc()` to prepare the values passed to `Program::createFunction()` even if we don't need them now, that's a possible optimization for a later commit.
