  "message": "In arena, allocate strings on dedicated string blocks so that they can be efficiently destructed.\n\n- StringBlocks form a chunked linked list in which all nodes other than the first are full. When sizeof(void*)\u003d\u003d8 and sizeof(std::string)\u003d\u003d24, there are 21 strings per 512 byte StringBlock.\n- We no longer need to store cleanup nodes for std::string (when using AllocateAlignedWithCleanup) - instead we traverse the StringBlock list.\n- Template AllocAligned on is_string in order to avoid comparing the destructor against the string destructor on the allocation hot path.\n- Remove specialized cleanup blocks for string/cord. This allows for simplifying the allocation and cleanup code, and we still save memory due to no longer needing cleanup nodes for most strings.\n\nPiperOrigin-RevId: 488736123\n",
