I'm not sure what needs to be done in spec-land to make valueOf work
correctly, but in implementation-land it needs the same unforgability
mitigations as toString.

Here are a couple test suites that might be helpful:

http://trac.webkit.org/browser/trunk/LayoutTests/fast/dom/Window/Location

In particular the location-override-* and location-shadow-* tests.
Also http://webblaze.cs.berkeley.edu/tests/window-location/ has a test
suite (which might overlap substantially with the former).
