Fix membership assignment for old-fashioned prototype members (#599)
Fixes #598 This _changes behavior_: previously in the case of ```js /** base */ var Foo = function Bar() { { /** */ this.baz = 0; } }; ``` We assigned baz to Bar. Now we will assign Baz to Foo. I believe this is right, since in JavaScript Bar is not actually bound in this code.
