CheckNNConstraintFetch: Fill all of ConstrCheck in a single pass
Previously, we'd fill all fields except ccbin, and only later obtain and
detoast ccbin, with hypothetical failures being possible. If ccbin is
null (rare catalog corruption I have never witnessed) or its a corrupted
toast entry, we leak a tiny bit of memory in CacheMemoryContext from
having strdup'd the constraint name. Repair these by only attempting to
fill the struct once ccbin has been detoasted.
