This test was modified in D104958. Invoking opt with -{passname} (vs
-passes={passname}) without -enable-new-pm={0|1} is now ambiguous and
dependent on how LLVM was configured. Drop the LPM runs rather than
fix since there unlikely to be any users still on LPM that rely on the
behavior in this test.
