It looks like the test is failing the pre-merge build:

By the way, I just noticed that this uses `-emit-fir`, would it be possible to test with `-emit-hlfir`?

The rational is that some optimizations/arith patterns are applied between lowering and the output of -emit-fir, so for tests that generate and tests a lot of arith ops, using `-emit-hlfir`  decrease the chances this test need to be updated when modifying the pipeline or arith canonicalization patterns.
