This has been handy locally for debugging cloning issues. The NodeIds are assigned sequentially on creation and included in the dumps and the dot graphs. No measurable memory increase was found for a large thin link. I only changed one test (Transforms/MemProfContextDisambiguation/basic.ll) to actually check the emitted NodeIds, most ignore them.
