Don't pass the grouping target around unnecessarily.

Since commit 4f15e5d09de276fb77326be5567dd9796008ca2e made grouped_rel
set reltarget, a variety of other functions can just get it from
grouped_rel instead of having to pass it around explicitly.  Simplify
accordingly.

Patch by me, reviewed by Ashutosh Bapat.
