Ensure ttValue != VALUE_NONE in singular extension search The assert: assert(ttValue != VALUE_NONE); Could fire for multiple reasons (although is very rare), for instance after an IID we can have ttMove != MOVE_NONE while ttValue is still set at VALUE_NONE. But not only this, actually SMP is a source of corrupted ttValue and anyhow we can detect the condition: ttMove != MOVE_NONE && ttValue == VALUE_NONE even north of IID. Reported by Ronald de Man. It is so rare that bench didn't change. bench: 7710548
