AST generation fails when a column has over 183 columns

[Helge Heß]

For example the CoreData database of the Apple Notes application has a table called ZICCLOUDSYNCINGOBJECT, which has 184 properties.

Generation for this eventually crashes due to the recursion done in:

  func generateBindStatementForProperty(
         _ property : EntityInfo.Property,
         index      : Expression,
         trailer    : () -> [ Statement ] = { [] }
       ) -> ( Statement, didRecurse: Bool )

Probably need to flatten that. Maybe not do recursive binds for tables with that many columns at all.
