Unfortunately, size is not a precise way of differentiating primitives from array of pointers. We can still have the size of a primitive being the same as the size of an array (consider array with 1 element).
The specific use case for us is that when we lower these intrinsics, we need to know if we need to add the GC support for this (done in IR itself) or not. With opaque pointers without `elementttype` in the intrinsic, we lose this knowledge,
