Duplicate final initializes do not cause a compile error

[jtmcdole]

New test, language/ConstructorDuplicateInitializersTest.dart:

class Class {
  Class(var v)
    : field_ = v
    , field_ = 2 /// 01: compile-time error
  ;
  Class.field(this.field_)
    : field_ = 2 /// 02: compile-time error
  ;
  final field_;
}

main() {
  new Class(42);
  new Class.field(42);
}

dart2js fails to reject subtest 02:

  Class.field(this.field_)
    : field_ = 2 /// 02: compile-time error
  ;
