ARRAY_SIZE: check that argument is an array
It's a familiar pattern: some code uses ARRAY_SIZE, then refactoring
changes the argument from an array to a pointer to a dynamically
allocated buffer. Code keeps compiling but any ARRAY_SIZE calls now
return the size of the pointer divided by element size.
Let's add build time checks to ARRAY_SIZE before we allow more
of these in the code-base.
