Don't bother copying empty support arrays in a zero-column MergeJoin. The case could not arise when this code was originally written, but it can now (since we made zero-column MergeJoins work for the benefit of FULL JOIN ON TRUE). I don't think there is any actual bug here, but we might as well treat it consistently with other uses of COPY_POINTER_FIELD(). Per comment from Ashutosh Bapat.
