structs: bugfix in static-slot-ensure.
* struct.c (static_sot_ens_rec): This change is in the case
when a static slot is being ensured in a struct type which
already has that static slot by inheritance. In that
situation, the inheritance is severed and the struct gets its
own non-inherited slot of that name. Then all of the derived
structs are scanned. If any contain the original inherited
slot, it is updated to the new, non-inherited one. The bug
here is that we were copying the home_offs field of the
original inherited slot to the new one! This is wrong; the new
slot is not related to the original inherited one. The new
slot is a home slot and its own offset must be home_offs.
We can calculate that simply as its delta from the static slot
table base.
