I guess it depends on the scope of the PR? If it was about removing cc0,
then this patch would do. If it was about getting the generated code
also to be as close to what it was with cc0, then no, it cannot be closed.

OTOH, while the second patch (adjusting peepholes) does help, there are
other things in the pipeline - addition of new CC modes and enabling
compare elimination, adjusting rtx costs etc. I will continue to work on
them in my spare time and submit patches when ready.
