mips.c: Include tree-pass.h.
* config/mips/mips.c: Include tree-pass.h. (mips_reorg): Split in pre- and post-dbr_schedule parts. (mips_machine_reorg2): Move mips_reorg post-dbr_schedule parts here. (pass_mips_machine_reorg2): New machine specific pass. (insert_pass_mips_machine_reorg2): New pass plugin definition. (mips_option_override): Register the new pass. * rtl.h (cleanup_barriers): Remove prototype. (dbr_schedule): Likewise. * jump.c (cleanup_barriers): Make static. * reorg.c (dbr_schedule): Likewise.
