"from inline" is of course misleading here. I suppose the same issue might happen with templates where we'd warn once per instantiation? There's for sure a better way to exclude the CTOR/DTOR clones than checking DECL_ABSTRACT_ORIGIN. DECL_FROM_INLINE is nearly dead, it should probably be removed.=
