Don't run the objc-arc-contract pass when disable-llvm-optzns is passed. In pipeline setups where the swift-frontend is called twice; - the first time to create bitcode - the second time to generate object code from the bitcode (using disable-llvm-optzns) we don't want to run the objc-arc-contract pass twice. rdar://91908312
