Gets the size of the elements pointed to by the pointer operands, in bytes.
When adding an integer offset to a pointer (
PointerAddInstruction) or subtracting an integer
offset from a pointer (
PointerSubInstruction), the integer offset is multiplied by the
element size to compute the actual number of bytes added to or subtracted from the pointer
address. When computing the integer difference between two pointers (
the result is computed by computing the difference between the two pointer byte addresses, then
dividing that byte count by the element size.
