Object.defineProperty cross-browser testcase

In contrast with the implementation in IE8+ and FF3.7, WebKit ignores
properties which collide with native properties on DOM prototypes, and throws
an error when trying to define any property on a DOM element.

This was tested against WebKit nightly r56152, Mozilla Developer Preview 3.7
alpha 3, Internet Explorer 8 and Internet Explorer Platform Preview
1.9.7745.6019.
