Thanks for the review!

I split out the not and added an assert. Thankfully the fuzzer has quite a few finds of this ice so I was able to find another testcase that doesn't have any dead variables. The loop-constant seems to be a bit more challenging to get rid of.
I'll check the remaining testcases again just to make sure I didn't miss one.
