I assume you want to know if two load addresses are either identical,
have stride one (have a offset of +1) or some other more complicated stuff.
What might work is the following (entirely untested):
LoadInst *LoadOne = ...
LoadInst *LoadTwo = ...
Value *PointerOne = LoadOne->getPointer();
Value *PointerTwo = LoadTwo->getPointer();
const SCEV *PointerOneSCEV = SE->getSCEV(PointerOne);
const SCEV *PointerTwoSCEV = SE->getSCEV(PointerTwo);
// If this is a trivial offset we get something like 1*size...
