Renumbering insns is something we've discussed before, but we hadn't
done it because it starts to become a pain in the ass to debug the
optimizers -- tracking a particular insn as it moves through the
compiler becomes much harder.

At minimum we should emit translation tables into the debugging
dumps so that we can match things up; but perhaps we shouldn't
do this compaction at all and instead get passes to work off LUIDs.

Comments?
