Hmm... wouldn't we want the warning to be emitted if the source code was itself
of the form constructed by `(,fn ,@(cdr form))?
IOW I think we want that `byte-compile--check-arity-bytecode` call to be
elsewhere (in the code that actually compiles the code constructed by
`(,fn ,@(cdr form))).
Also, as a general rule I think we should try and refrain from emitting
warnings from the code in byte-opt.el (warnings should be independent
from optimizations).

I think the same holds here.
