[SelectionDAG] Allow FREEZE to be hoisted before integer SETCC. (#84241)
Teach canCreateUndefOrPoison that ISD::SETCC with integer operands can
never create undef/poison. FP SETCC is more complicated and will be
handled in a future patch.
Teach isGuaranteedNotToBeUndefOrPoison that ISD::CONDCODE is not
poison/undef. Its a special constant only used by setcc/select_cc like
nodes. This is needed since the hoisting will only hoist if exactly one
operand might be poison. setcc has 3 operand including the condition
code.
Recovers some regression from #84232.
