[Test] delete LPM RUNs in inline_nossp.ll

[nickdesaulniers]

Summary

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.

Fix this test for folks still using the OPM.

I think there is no user needing legacy PM + the specific ssp inlining behavior... So I'd just delete the legacy PM tests.

• remove tests, update commit message

• remove line from update_test_checks that I didn't mean to commit

Thanks!

More formal name is "legacy PM", not "old PM"

The abbreviation "OPM" may be a bit ambiguous
