I thought we already had this, but I guess I was thinking of
-Wsizeof-pointer-div instead...

Looks like a good idea for a warning.

But please don't make the diagnostic say "every element", since I hope all the
elements of an array have the same size, so you don't need to consider every
one of them ;-)
