 * SUMMARY: Testing  obj.__lookupGetter__(), obj.__lookupSetter__()

 * See http://bugzilla.mozilla.org/show_bug.cgi?id=71992

 * Brendan: "I see no need to provide more than the minimum:

 * o.__lookupGetter__('p') returns the getter function for o.p,

 * or undefined if o.p has no getter.  Users can wrap and layer."
