This change will suppress some unused argument warnings but I'll not call that "regression":) Various toolchains already do things like: Args.ClaimAllArgs(options::OPT_g_Group); Args.ClaimAllArgs(options::OPT_emit_llvm); Args.ClaimAllArgs(options::OPT_w); Hexagon and Myriad even do `Args.ClaimAllArgs(options::OPT_static_libgcc);` This diagnostic IMO has very low value.
