category is empty Currently, if we create a category in ObjC that is empty, we still emit runtime metadata for that category. This is a scenario that could commonly be run into when using __attribute__((objc_direct_members)), which elides the need for much of the category metadata. This is slightly wasteful and can be easily skipped by checking the category metadata contents during CodeGen. rdar://66177182 Differential Revision: https://reviews.llvm.org/D113455
