We want to disable uneval and Object.prototype.toSource code. To start we only plan on disabling both functions for non-chrome/content scripts, so I am only fixing those tests here.

I am making good progress getting linux64 green. Fixing js/xpconnect/tests/chrome/test_xrayToJS.xhtml is going to be a bit of work, because it uses toSource quite a bit. I am not sure yet what is causing the failure in devtools/client/dom/test/browser_dom_array.js, but it must be somewhere in the devtools code outside the test.

For test browser_net_prefs-reload.js, I am not sure about this change firstValue/currentValue seems to be different types numbers, strings, objects.
toString is maybe not the best way to compare those values.

I am not sure we should really remove toSource from Codegen.py, but I wanted to make sure to follow the test comment.

Using JSON.stringify in dom/tests/mochitest/chrome/test_clonewrapper.xhtml might not be the best solution, because
the testObject contains ImageData objects.

Because toSource is available to chrome code, we need to adjust some parts where toSource is missing because of content contexts.
We can remove most these changes when we remove toSource everywhere.

I replaced a single use of toSource with JSON.stringify in test_fetch_cors_sw_reroute.html.
