Fix oversight in construction of sort/unique plans for UniquePaths.
If the original IN operator is cross-type, for example int8 = int4,
we need to use int4 < int4 to sort the inner data and int4 = int4
to unique-ify it. We got the first part of that right, but tried to
use the original IN operator for the equality checks. Per bug #5472
from Vlad Romascanu.
Backpatch to 8.4, where the bug was introduced by the patch that unified
SortClause and GroupClause. I was able to take out a whole lot of on-the-fly
calls of get_equality_op_for_ordering_op(), but failed to realize that
I needed to put one back in right here :-(
