As I see currently there are tests for the optimizations `simplify-hlfir-intrinsics-*` , but I could not find explicit checks for simplifying the other intrinsics based on the flag -O1. So I just added checks in the same format as for the previous simplifications.

This should cover what you mention, since it is tested that (a) the pass `SimplifyHLFIRIntrinsics` is called upon setting the -O1 flag, and (b) `SimplifyHLFIRIntrinsics` simplifies products as expected.

Let me know if you'd like something done differently.
