[LV][NFC] Tidy up partial reduction tests with filter-out-after option (#129047)
A few test files seemed to have been edited after using the update_test_checks.py script, which can make life hard for developers when trying to update these tests in future patches. Also, the tests still had this comment at the top ; NOTE: Assertions have been autogenerated by ... which could potentially be confusing, since they've not strictly been auto-generated. I've attempted to keep the spirit of the original tests by excluding all CHECK lines after the scalar.ph IR block, however I've done this by using a new option called --filter-out-after to the update_test_checks.py script.
