Added auto-tupling.
Auto-tupling should satisfy the following spec.
1. An application `f(args)` where `f` is a non-overloaded method which has a single, non-repeated parameter as its
first parameter list and where args consists of two or more arguments is expanded to `f((args))`.
2. A constructor pattern `C(args)` where `C.unapply` is a non-overloaded method which has a single, non-repeated parameter as its first parameter list and where args consists of two or more arguments is expanded to `C((args))`.
Auto-tupling can be disabled by language feature "noAutoTupling".
