The UpdateTestChecks tool itself does not care about which pass manager that is used in the opt invocation. So the lit tests that are verifying the behavior of the UpdateTestChecks tool is updated to use the new-PM syntax (-passes=) when specifying the pass pipeline in the test cases that are used for verifying the UpdateTestChecks tool.
