[PATCH] D30124: [ARM] Fix insert point for store rescheduling.

In ARMPreAllocLoadStoreOpt::RescheduleOps, LastOp should be the last operation which we want to merge. If we break out of the loop because an operation has the wrong offset, we shouldn't use that operation as LastOp.

This patch fixes some trivial cases where we would fail to move stores.
