> Can your add also IR testcase from that PR? (To show that Instcombine can fold it)

This commit is actually not enough to fix that PR, instcombine will still not be able to simplify the IR because it doesn't understand that `icmp ugt float*, inttoptr (i64 523 to float*)` is a `icmp` with a compile time constant.
Let me see if I can massage the IR to work around this issue.
