FYI, I'll probably remove `FPEncoding` in a subsequent patch. As we discussed offline last time it seems more appropriate to specialize `FPRep` for `FPType::X86_Binary80` instead of having specific logic in a generic implementation. The current state is confusing and doesn't scale if we have to support other types like `bfloat16`.
