50bec6f8c4 LoopVectorizer: Add a basic cost model which uses the VTTI interface.

bf8772ed2c Vectorize: teach cavVectorizeMemory to distinguish between A[i]+=x and A[B[i]]+=x.
If the pointer is consecutive then it is safe to read and write. If the pointer is non-loop-consecutive then
it is unsafe to vectorize it because we may hit an ordering issue.
