The nominal distinction is that the Language files contain what you can know about or need to do with a given language without having a process and thus a live runtime to query. The LanguageRuntimes are supposed to be about what you can gather from the actual runtime, or what you need to do to handle things like "stepping into steps across ObjC method dispatch functions" or "stepping into std::function steps in to the target function". Given this distinction you'd actually expect the two to be independent of one another, but then it turns out that in both ObjC and Swift, you can't actually know the sizes of objects, or the offsets of ivar members until you have a running process. So things you'd think the Language would know actually require the LanguageRuntime...
