Fix possible Assert failure in verify_compact_attribute()HEADmaster
Sometimes the TupleDesc used in verify_compact_attribute() is shared among backends, and since CompactAttribute.attcacheoff gets updated during tuple deformation, it was possible that another backend would set attcacheoff on a given CompactAttribute in the small window of time from when the attcacheoff from the live CompactAttribute was being set in the 'tmp' CompactAttribute and before the Assert verifying that the live and tmp CompactAttributes matched. Here we adjust the code to make a copy of the live CompactAttribute so that we're not trying to Assert against a shared copy of it.
