return `llvm::ArrayRef<uint8_t>` and get rid of the `size_t &available_bytes` parameter as the size of the returned ArrayRef will be sufficient. Also, please provide a default implementation that returns an empty array so subclasses that don't override this don't have to have change to their header and implementation file.
