055e4ff3 - [VPlan] Don't narrow op multiple times in narrowInterleaveGroups.

[VPlan] Don't narrow op multiple times in narrowInterleaveGroups. Track which ops already have been narrowed, to avoid narrowing the same operation multiple times. Repeated narrowing will lead to incorrect results, because we could first narrow from an interleave group -> wide load, and then narrow the wide load > single-scalar load.
