Thanks for sending the patch.  Procedural note: patches should be sent
to gcc-patches@gcc.gnu.org, and should have a ChangeLog entry.

I don't think it is appropriate to change the meaning of
forwarder_block_p.  And I'm not sure why you need that patch anyhow,
considering the existing code in cleanup_tree_cfg_1.

Also you should ideally add a test case.

Thanks.
