I don't know about the serialization issues - if you load all global
decls all the time we should be fine, but otherwise you would need to be
able to re-cherry-pick more globals during local optimizations (or de-serialize
all reachable globals like we have now in referenced_vars, but do not
put the into the referenced_vars immediately).
