Hi,
I included the outstanding minor remarks and believe everything is OK'ed
now. Still posting the ChangeLogs that I omitted before continuing.
I'd expect some fallout on other targets (hopefully nothing major) since
rtx costs are handled differently now for this code path.
Regards
Robin

In order to achieve that, this patch goes through all relevant SETs
