  "message": "[ADT] Modernize SparseMultiSet to use llvm::identity_cxx20 (NFC) (#164361)\n\nThe legacy llvm::identity is not quite the same as std::identity from\nC++20.  llvm::identity is a template struct with an ::argument_type\nmember.  In contrast, llvm::identity_cxx20 (and std::identity) is a\nnon-template struct with a templated call operator and no\n::argument_type.\n\nThis patch modernizes llvm::SparseMultiSet by updating its default\nkey-extraction functor to llvm::identity_cxx20.  A new template\nparameter KeyT takes over the role of ::argument_type.\n\nExisting uses of SparseMultiSet are updated for the new template\nsignature.",
