Modified files:
    src/backend/optimizer/plan: planner.c setrefs.c subselect.c
    src/include/optimizer: subselect.h

Log message:
    Reconsider mechanism for marking sub-selects that are at top level of
    a qualification clause (and hence can get away with being sloppy about
    distinguishing FALSE from UNKNOWN).  We need to know this in subselect.c;
    marking the subplans in setrefs.c is too late.
