This is just hacking around the offloading entires. I wanted to use the same struct and handling for convenience, but right now there's no basic flag for what the kind of the thing is. Previously we just had functions and globals, if the size is zero it's a global. I added a third thing which can also be checked if the address is nullptr currently. I want to overhaul this in the future but I'm hoping to get this stuff working first.
