If that's the case, maybe we can just change FieldDecl::isZeroSize() to say the field is zero size? So essentially, we pretend all empty fields are no_unique_address. Nothing in codegen should care if we treat an non-zero-size empty field as if it's zero-size.

(sorry if I'm jumping in without enough context... ) - couldn't the inverse be true, then - that codegen should ignore if something `isZeroSize` or not? So lldb doesn't have to put any particular value here?
