Nit, since all we actually want is VecRegSize, consider making at least 'AS' a temporary:

Value *Ptr = LI->getPointerOperand();
unsigned VecRegSize = TTI.getLoadStoreVecRegBitWidth(Ptr, Ptr->getType()->getPointerAddressSpace());

This way readers have to carry one less local variable. Same elsewhere.
