Details

As we are already tracking types of heap objects and their slots, we should be able to use that information better in laying out objects in a tagless fashion. (Thomas Wuerthinger from Oracle had a talk on this at JSTools'13, though I can't seem to find a link to the work or the talk at the moment.) Just like we can type-specialize *code* and bail out when those assumptions fail, we can also type-specialize *data* and fall back to a tagged representation

Ended up adding Unboxed objects, then removing them later.
