Truffle-DSL: Several new features implemented: Implementation of a new code generation layout which shares code between generated nodes. Declaration order of specializations is now used as specialization order. Specializations do no longer perform fallthrough on respecialization, they now always respecialize from the first specialization. Implemented support for contains relations between specializations. Improved reachability error messages. Preliminary support for @Implies.
