  -----------
  [LAA] Make getPointersDiff() API compatible with opaque pointers

Make getPointersDiff() and sortPtrAccesses() compatible with opaque
pointers by explicitly passing in the element type instead of
determining it from the pointer element type.

The SLPVectorizer result is slightly non-optimal in that unnecessary
pointer bitcasts are added.
