+We're now working with node entry addresses *plus one*. There is some
+information stored right before the node entry, such as arity, which is used in
+the garbage collector (among other places?). This was previously fetched with
+`[r6,#-4]` for example, and should now be fetched with `[r6,#-5]` to
+accommodate for this. This is done in cg:gc-flipped `56d30f5` and
+rts:gc-flipped `9f522d3`.
