jump_label: Implement generic support for relative references
To reduce the size taken up by absolute references in jump label
entries themselves and the associated relocation records in the
.init segment, add support for emitting them as relative references
instead.
Note that this requires some extra care in the sorting routine, given
that the offsets change when entries are moved around in the jump_entry
table.
