example: OP_COPY must destroy any old pseudo state
Toto, I have a feeling We're not in SSA land any more.
(Not that it really helps. The example compiler not only had SSA
assumptions, it also depended on liveness information and insn->def
state, both of which are destroyed by the un-ssa phase. So this is
really a small bandage around a much larger problem, and doesn't really
fix anything fundamental).
