Well, sort of.  It adds to label_value_list, but doesn't update 
existing computed gotos to jump to the new labels.  It means that
if you were to rebuild the CFG from scratch afterward you wouldn't
get the same answer.

What's the test case for this?  I would have expected all labels
visible to computed jumps to already exist at the tree level,
and thus we could derive the rtl list from that.
