  [LegalizeTypes] Avoid creating an unused node in ExpandIntRes_ADDSUB. NFC

The Hi result is sometimes calculated a different way and this
node goes unused. Defer creation until we know for sure it is neeeded.

The test changes is because the node creation order changed the names
in the debug output.
