This is followup of #151

With big number of nodes we have huge RAM consumption in ModelMapping class

objects bytes class
18,750 413,982,672 Dictionary<Xtensive.Orm.Model.TypeInfo, Xtensive.Sql.Model.Table>+Entry[]

We can represent this mapping as Table[] array.

Then our RAM consumption will be 1100*8*18750 ~= 165M.
2.5 times less, saving 248MB
