I do wonder if we should just check the argument count at the very beginning of
`CheckBuiltinFunctionCall` -- we already call `GetBuiltinType`, and while we'd
need to check for varargs and custom type checking flags it seems like it would
be more robust to handle the bulk of these function's arg count checks
immediately.
@AaronBallman added that call originally so I wonder if he knows why we can't
do this :D
