[LV] Enable the LoopVectorizer to create pointer inductions
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, which produces much less instructions than the previous approach of creating scalar getelementpointers and glue them together to a vector.
