Truffle-DSL: some fixes and optimizations to the generated code. Fixed polymorphic specialization nodes could still reference children in some cases. Removed generation of getCost methods since they were very expensive to call. Removed generation of copyPolymorphic, setNext0. Made generated executeGeneric0 and executeAndSpecialize0 final.
