The following code generators use FOR_EACH_BB[_REVERSE] in the target

The very first thing that ia64_reorg does is
compute_bb_for_insn ();
Just taking a quick look, I don't see any bb usage in the s390 port,
and I see bfin and frv calls compute_bb_for_insns also. mt isn't using
the full bb->insn mapping table, it is only using the bb tail, so it is
probably not broken.
I think most basic block info should still be there at the end, it is
the bb->insn mapping table that disappears. See the code for
pass_free_cfg. This table can be recomputed if you need it.
