Zero sized fields are messing up the offset calculations when we import C++ fields to Swift. We assume that the size of the field is determined by the type of the field. This is not true for fields marked with no_unique_address. Those fields can have 0 size while the sizeof(decltype(field)) is still 1. rdar://143907490
