Please clean up the PR, there are old, already merged, commits in there.
Can you come up with a better commit title? Don't forget prefixing with arcv: and using --signoff.

Don't just comment these out. Remove the lines if they need to be removed.
Also, don't we need something like next_non_dbg_insn? That keeps invoking next_insn in a loop until it finds either a non-debug insn or null?
during scheduling (before ira/fusion/after ira) certain conditions that enable fusion (thus sequence ordering) take into account the presence of debug instructions. But debug instructions shouldnt influence instruction order.
