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: keep a set of all code_blocks in the code_heap

This way looking up code blocks by return address is an O(log n) set lookup rather than an O(n) linear scan.
