  "message": "Store `alignof(slot_type) - 1` instead of `alignof(slot_type)` in raw_hash_set policies.\n\n`PolicyFunctions::slot_align` and `DtorPolicy::slot_align` are replaced with `slot_align_mask` (`alignof(slot_type) - 1`), and `RawHashSetLayout` / `CreateForSmallNonSooGrowth` take the mask. A new `AlignUpToMask(offset, mask)` computes `(offset + mask) \u0026 ~mask`, which avoids negating the alignment at runtime: on x86-64 with BMI1 it compiles to `add` + `andn` instead of `lea` + `neg` + `and`, and callers that need the value for both allocation and deallocation only keep one value live instead of `align` and `-align`.\n\nPiperOrigin-RevId: 1007521147\n",
