[llvm] [ValueTracking] Expand cmpExcludesZero to optionally work with non-constant RHS (PR #69364)

Could you please provide the original motivating case for this? I think this goes beyond what is reasonable to handle in ValueTracking, and it would be best to handle your use case via LVI+CVP instead, if this is possible.
