URL: https://github.com/llvm/llvm-project/commit/173df3dd5f9a812b07f9866965f4e92a982a3fca DIFF: https://github.com/llvm/llvm-project/commit/173df3dd5f9a812b07f9866965f4e92a982a3fca.diff LOG: [clang][CFG][NFC] A few smaller cleanups Use dyn_cast_if_present instead of _or_null, use decomposition decls, and a few other minor things.
