Generational marking is off in ToT, but some of the machinery to make it work isn't fully disabled which is causing regressions on dromaeo. We should disable more things to get to a point where the patch is no regression when ENABLE_GGC == 0 because it would be nice to have the option to disable generational collection for diagnosing any potential GGC bugs.

I ran dromaeo and it looks like this patch fixes the obvious regressions.
