nit: This block looks like it was only introduced for the NestedClassLiteral.
Can we remove it and outdent everything one level?

Done.

-    NestedClassLiteral nested_class_literal(this, lit);
-    EnterBlockScopeIfNeeded block_scope_state(
-        this, lit->scope(), lit->EntryId(), lit->DeclsId(), lit->ExitId());

     if (lit->extends() != NULL) {
       VisitForStackValue(lit->extends());
     } else {
