    Implement fmap/coerce rules
    
    Implement fmap/coerce rules for Map, Sequence, and Tree. One concern:
    unfortunately, implementing the RULES forces the LANGUAGE to be turned
    from Safe to Trustworthy.  This is rather sad. An alternative would be
    to do this in another module, but orphan rules are not so lovely either.
