In the loop f, the loop vectorizer is able to use a scalar address throughout the segmented accesses.
In g, where not every segmented field is written back to, it's kept around as a widened vector of pointers, even though we only use the first element of it.
`legalizeAndOptimizeInductions` in VPlanTransforms.cpp may not be catching this case.
