With optimization, it looks like we die because df_insn_change_bb can handle
insn_info being NULL but it can't handle insn_info->defs (or uses or eq_uses)
being NULL and that is what is happening with -O2.  When no optimization is
being done then the failure looks different.  I believe this is due to the
dataflow merge.
