I have a different patch which I'll submit next week after some more
testing. The assert in cfgrtl is unnecessarily broad and really only
needs to trigger if -freorder-blocks-and-partition; there's nothing
wrong with entering cfglayout after normal bb-reorder.
I've also tested that Blackfin still benefits from the hw-doloop
reordering code and generates more hardware loops if it's enabled. So we
want to be able to run it at -O2.
