dart2js fails language/call_constructor_on_unresolvable_class_test/{03,06}

[peter-ahe-google]

The specification says:

"It is a compile-time error to use a built-in identifier other than dynamic as a type annotation."

"library" is a built-in identifier, but it contains these two subtests:

    new library.A(); /// 03: static type warning
  new library.A(); /// 06: runtime error

[peter-ahe-google]

Actually, this is not a type annotation, and specification does not prohibit the use of built-in identifiers as library prefixes.

Marked this as blocking #5519.

Dart2js allows using "library" as a prefix but fails tests/language/built_in_identifier_prefix_test.dart which is tracked by issue #6972.
