367b88e6 - Add regression test for redundant strong_retain/strong_release pair (#89473)

Add regression test for redundant strong_retain/strong_release pair (#89473) Locks in that closure specialization no longer leaves a redundant strong_retain/strong_release pair around a non-escaping closure call that captures a borrowed class reference. Fixed between Swift 6.3 and 6.4; test guards against future regression. Resolves #82155
