Frog crashes instead of reporting an error

$ cat fisk.dart
class T {
  toString() => "class T";
}

class Foo<T> {
  m() => new T();
}

class Bar extends Foo {
}

main() {
  print(new Bar().m());
}

That's not actually a "crash" ... it's an internal error: "no constructors on type parameters yet" :)
Should be a really simple fix, just changing the error level and making sure we have the right span.

Removed this from the FrogEditor milestone.
Added this to the Release1.0 milestone.
