DESCRIPTIVES: Make Z score calculation honor SPLIT FILE.

Until now, DESCRIPTIVES has not supported SPLIT FILE in Z score
calculations.  That is, Z scores have been calculated on the basis of a
single group for the entire file, which doesn't make any sense.  This
commit properly implements Z score calculation on a per-split group basis.

Bug #16351.
