Sorry, jumping in here without a lot of context, but the change in
`%struct.WithEmptyField` seems wrong, doesn't it? Like that is a change in
layout/ABI break/bad thing? I guess I'm missing something about why that change
in layout would be acceptable? (maybe padding - if NonPOD gets aligned, such
that the structure isn't changing layout after all?)
