vm: stage code block map fixup properly for GC
...
Don't update the map until the very last thing, and pass untranslated addresses to the iterator functors. Somewhat complicated by the fact that, for startup_fixup, the map is initialized with fixed-up values, so the fixup functor needs a flag indicating whether it operates with a fixed or unfixed code heap map.

vm: during tenuring stage of aging collection, if tenured space fills up, it would attempt a to_tenured collection. this will succeed if all roots were tenured. however, this is unsound, because there's now an untraced segment of tenured space. fix: if tenuring fails, go on to do a full collection instead
