Currently, pointer inductions are scalarized by the LoopVectorizer. Individual getelementptrs are built to create an address from the induction variable and are then inserted into vectors to be used by vector loads and stores. This patch enables the LoopVectorizer to build a phi of pointer type and provide the vector loads and stores with vector type getelementptrs built from the pointer induction variable.
