Subject: [PATCH] Run LargeTestSuite with the old backend once

The LargeTestSuite_OB report in heavy_tests is from 2023 (v1.22), as
f1b2023 removed the OB entry. Add it again for one run, to compare
the old backend with the new backend. The entry is the NB entry
without the new backend flags and with -O0, as the other OB entries.

Remove the entry after the run.
