Don't consider enum elements to be initializers.

Remove an odd enum hack we've had since before we had initializers, which
treated the cases of an enum as initializers that accept a value of
the type stored in the initializer. For example, given a typical
optional type definition like

  enum Optional<T> {
    case None
    case Some(T)
  }

One could directly construct an optional as, e.g.,
Optional<Int>(5). While this is the right thing for optional, it
doesn't make sense in the general case. Remove this behavior, and
explicitly add initializers in places where they make sense.
