Address ccvalid/ccnoinherit in TupleDesc support functions.
equalTupleDescs() neglected both of these ConstrCheck fields, andCreateTupleDescCopyConstr() neglected ccnoinherit. At this time, theonly known behavior defect resulting from these omissions is constraintexclusion disregarding a CHECK constraint validated by an ALTER TABLEVALIDATE CONSTRAINT statement issued earlier in the same transaction.Back-patch to 9.2, where these fields were introduced.
