This pr creates the object file for the carbon code that returns either 0 or 1. The command to convert the object code to binary is `clang <object_file_name> -o <binary_name>` --------- Co-authored-by: Farzana Ahmed Siddique <fasiddique@google.com> Co-authored-by: Richard Smith <richard@metafoo.co.uk>
