URL: https://github.com/llvm/llvm-project/commit/59f8af35b6bb15c0794873786cb34c7867be357b DIFF: https://github.com/llvm/llvm-project/commit/59f8af35b6bb15c0794873786cb34c7867be357b.diff LOG: [NFC][Clang] Adopt simplified `getTrailingObjects` in DeclFriend (#140081) - Adopt non-templated `getTrailingObjects` in DeclFriend, DeclGroup, and DeclObjC - Use indexing into ArrayRef returned by `getTrailingObjects` and eliminate explicit OOB asserts.
