Implement unused pattern bindings, continued (#6518)
Implementation of unused pattern bindings #2022, continued. Whereas previous PR #6460 took care of parsing, and PR #6479 prepared the stage by using _ in some test cases, this PR has the the actual implementation, using a simple dataflow analysis. --------- Co-authored-by: Burak Emir <bqe@google.com> Co-authored-by: jonmeow <jperkins@google.com>
