Whether two types can be compared, e.g. as a pair of join keys: they must be
in the same comparison class, where the abstract Date also compares with
StrictDate and DateTime.
NOTE: StrictDate and Timestamp are not compatible. The engine runs such a
comparison, but it only ever matches timestamps at midnight. The engine
compiles == between any two types, so this check can't be left to it.
