Use ARRAY_SIZE instead of dividing sizeof array with sizeof an element

Semantic patch information: This makes an effort to find cases where ARRAY_SIZE can be used such as where there is a division of sizeof the array by the sizeof its first element or by any indexed element or the element type. It replaces the division of the two sizeofs by ARRAY_SIZE.
