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. Differential Revision: https://reviews.llvm.org/D104784
