  [DomTreeConstr][NFC] Resize NodeInfos once on construction (#211998)

This avoids frequent size checks when accessing node infos. All numbered
graphs support getMaxNumber().

Also move away from BB->getParent() as preliminary work for numbering
VPlan blocks -- there, getParent() has a different meaning.
