Previously, it was only in the GatherScatterFlattenOpt optimization pass that we added the per-lane offsets when we were indexing into varying data. (Specifically, the case of float foo[]; int index; foo[index], where foo is an array of varying elements rather than uniform elements.) Now, this is done in the front-end as we're first emitting code. In addition to the basic ugliness of doing this in an optimization pass, it was also error-prone to do it there, since we no longer have access to all of the type information that's around in the front-end. No functionality or performance change.
