- Split the `kcfi_unchecked` attribute into a separate patch.
- Based on feedback from kernel developers, switched to 32-bit type identifiers, added the `llvm.kcfi.check` intrinsic with arch-specific lowering, and added sections for locating both type identifiers and traps.
- Addressed the remaining review comments.
