URL: https://github.com/llvm/llvm-project/commit/a44ee8ec1c87be76e147d97f3be90a7e8630421b DIFF: https://github.com/llvm/llvm-project/commit/a44ee8ec1c87be76e147d97f3be90a7e8630421b.diff LOG: [TableGen] Use heterogenous lookups with std::map (NFC) (#115633) Heterogenous lookups allow us to call find with StringRef, avoiding a temporary heap allocation of std::string.
