> D110752 <https://reviews.llvm.org/D110752> is not corrupting IR, it happened because we were looking at a constant's users, which is not a thing that makes sense to do (e.g. look at all users of the constant false).

Yep, what it did doesn't make any sense because it was a bug. Since here we're discussing a debugging option, in my opinion it makes sense to take such cases into account.
