  llvm-reduce: Avoid using constantdata uselistorder in thinlto test (#136288)

This also demonstrates a bug that's a consequence of the two different
paths for the single and multithreaded cases. The parallel path goes
through bitcode serialization and does preserve the uselistorder. It
therefore survives and we can observe a reduced uselistorder with deleted
instructions. In the CloneModule case, nothing is reduced.
