[PATCH 2/3] ARM cost model: Address computation in vector mem ops not free

[Nadav Rotem]

The cost model part LGTM.  The Loop Vectorizer does not use the cost model analysis itself because it needs to check the costs of instructions that have not yet been generated. We need to change the loop vectorizer cost model to use this API. It could be a bit tricky because in some cases we don't use the original GEP because we widen the load/store.
