Summary: This change teaches DSE that the atomic memory intrinsics are stores that can be eliminated, and can allow other stores to be eliminated. This change specifically does not teach DSE that these intrinsics can be partially eliminated (i.e. length reduced, and dest/src changed); that will be handled in another change.
