Title: Bug489326 builtin objects (from 'ES5-Test262 progress' pull request)

This part of mozilla/rhino#39 does not involve any public API changes but merely updates the built-in objects to work in a more spec-compliant way. For the most part this affects handling of undefined arguments, missing methods to change attributes in IdScriptableObjects instances (i.e. missing setInstanceIdAttributes() overrides) and wrong execution order of spec algorithm steps.
