Kill nameSetElems in rnCmdTop

This change isn't necessary for determinism. appAName, choiceAName,
loopAName all have pre-allocated Uniques and their relative order
can't change. I opted to use nameSetElemsStable here because:
* the cost is negligible
* it's less fragile than just documenting

Test Plan: ./validate
