Basically that is because I don't generate the code needed to check
the argument count when --full-tailcalls. This is a bug. Of course
the fact that I have these plans for a new super-duper calling convention,
and checking argument count depends on the calling convention, and I'm
way backlogged on things means I probably won't fix it soon. But patches
gratefully accepted!
