Jonas Paulsson 6dc3e22b57 [DAGTypeLegalizer] Handle ZERO_EXTEND of promoted type in WidenVecRes_Convert. ...

On SystemZ, a ZERO_EXTEND of an i1 vector handled by WidenVecRes_Convert()
always ended up being scalarized, because the type action of the input is
promotion which was previously an unhandled case in this method.
