[PATCH] middle-end/113576 - zero padding of vector bools when expanding compares

The following zeros paddings of vector bools when expanding compares and the mode used for the compare is an integer mode. In that case targets cannot distinguish between a 4 element and 8 element vector compare (both get to the QImode compare optab) so we have to do the job in the middle-end. Bo
