#1341 Some classes have a lot more instance methods than expected

[Erich]

In 5.0, classes .Bag, .Directory, .Queue, .Relation, .Set, and .Table claim that they have significantly more instance methods than what they had in 4.2.

            class~methods(.nil)~allIndexes~items

 class      4.2   5.0
.Bag          9    51
.Directory   22    52
.Queue       30    68
.Relation    25    51
.Set          8    47
.Table       16    47

They seem to have added their own implementations of e. g. CLASS, COPY, DEFAULTNAME, HASHCODE, HASMETHOD, IDENTITYHASH, INSTANCEMETHOD, INSTANCEMETHODS, ISA, OBJECTNAME, OBJECTNAME=, REQUEST, SEND, SENDWITH, START, STARTWITH, and STRING (amongst others).

.StringTable is another example with all those additional instance methods apparently added.

Fix committed [r10950]. This probably needs a thorough retesting.
