  -----------
  [clang] Follow-up fixes for offsetof unsigned index change (#207808)

- Rename CastNoOverflow to CastAPToOffsetIndex for clarity
- Add parentheses in overflow guard condition in InterpBuiltin.cpp
- Improve comment explaining why 0x8000000000000000 is rejected

AI Tool Use: GitHub Copilot (Claude Sonnet 4.6) was used to assist in
identifying and drafting the fix. The fix was reviewed, tested, and
validated manually.
