Subject: [PATCH] harness: Add clarifying comments about inaccessible
 intrinsics

As far as I know, %AsyncFromSyncIteratorPrototype% and
%ForInIteratorPrototype% are not (and not intended to be) accessible to
ECMAScript user code, so they are impossible to test directly. Add a
clarifying comment, and make the source expression consistent ('' vs.
'undefined').
