Zi Xuan Wu	49d60fdc2e	[DAGCombiner] Do not generate ISD::ADDE node if adde is not legal for the target when combine ISD::TRUNC node ... Do not combine (trunc adde(X, Y, Carry)) into (adde trunc(X), trunc(Y), Carry), if adde is not legal for the target. Even it's at type-legalize phase. Because adde is special and will not be legalized at operation-legalize phase later.
