  "message": "Pass small trivial keys by value in SwissTable lookup and hash/eq helpers.\n\nMove `ShouldPreferPassByValue` (and its helpers) to `type_traits_internal` in `meta/type_traits.h`, require `std::is_trivially_copy_constructible_v\u003cT\u003e` in `ShouldSemanticallyPreferPassByValue`, and introduce `ConstParamT\u003cT\u003e` which passes types satisfying `ShouldPreferPassByValue\u003cT\u003e` by value (`const T`) rather than by reference (`const T\u0026`).\n\nUse `ConstParamT\u003cK\u003e` in `FindLargeKey\u003cK\u003e`, `HashKey`, and `EqualElement` (and `ShouldPreferPassByValue\u003cT\u003e` in `HashSelect::HashValueProbe::Invoke`) so small trivial keys stay in registers across `find_large`, `find_or_prepare_insert_large`, `PolicyTraits::apply`, and `AbslHashValue` calls instead of spilling to the stack and reloading through a reference.\n\nPiperOrigin-RevId: 991223700\n",
