The thunks we're talking about push an index onto the stack and then
call a function, so technically we could pre-generate lots of thunks at
compile time that do this but it'd put an upper limit on the number of
vtable entries you could have which I'm not keen on.
They might also push an object ptr as well, I don't remember ...
