If the SDNode is used it can pick up the wrong results number, for example looking at the known bits of the first result where it should be looking at the second. The SDValue is already present as the SelectCodeCommon checks move from parent to child, pass the SDValue through to CheckNodePredicate as Op so that it can use it if necessary. SDNode *N is still generated, keeping most PatFrags the same. Fixes #137274
