The assertions in nsINode and nsWrapperCache are to eagerly catch
failures to override those methods.
The classinfo change for XULTreeBuilder is needed because one of those
is returned via an nsIXULTemplateBuilder attribute on XULElement.
Alternately, I could mark it notflattened in Bindings.conf, but Enn
said he prefers this anyway.
The change to the QI impl in BindingUtils is needed because when
XPConnect converts an IID from C++ to JS it makes is an nsJSID, not an
nsJSIID. We've run into this before, sadly.
I removed "id" from nsIDOMXULElement because it's already on Element.
I suppose I could have left it there, but this seems cleaner.
The nsJSIID::HasInstance changes are needed to support XBL-implemented
interfaces. Sadly, this does mean that if the underlying object QIs
to something but we didn't put those props on the WebIDL we'll end up
testing true for instanceof but not exposing the props. I don't see
an obviously better way. We should work on killing off uses of
"instanceof someinterface".
The browser.js change is needed to avoid throwing exceptions during
browser-chrome tests that are now getting reported because our
swapFrameLoaders is no longer an XPConnect method.

This bug happens when we take the !useSandbox path. Basically, when the code
throws, we can end up with garbage in *aRetValue while still returning true
from EvaluateString. It looks like the convention is for these kind of eval
functions to return success even for invalid code, so lets just make sure we
check things a bit better.
This crashtest is kind of half-baked in the sense that it doesn't actually
crash without the rest of the patch. But the testcase here involves a lot of
undefined behavior (what ends up getting left in *aRetValue) during a call
to window.open (which spins the event loop, etc). I already sunk about half
an hour into trying to make it crash, so I'm just going to go with this for
now.
