[PATCH] Add emulated scatter capability to the vectorizer

This adds a scatter vectorization capability to the vectorizer without target support by decomposing the offset and data vectors and then performing scalar stores in the order of vector lanes. This is aimed at cases where vectorizing the rest of the loop offsets the cost of vectorizing the scatter.
