Thank you for fixing this. The change looks good to me once you have added a test.

I would test this by checking that hlfir.min and hlfir.max are not modified by the pass for a few types that aren't integers or floating point. See `flang/test/HLFIR/minval-elemental.fir` for an example test for this pass.
