With the current compiler it is impossible to expose the bug in the block ordering computation.
Consequently, there is no observable change in behavior and thus no news item is necessary.

At a glance I believe this is correct. Looping Thomas in as a reviewer as I believe he's been working in the compile code recently.

I won't say "recently" (I looked at peephole.c the last couple of days, but not compile.c), but I'm familiar enough. The new code does look a lot more sensible than reversing twice.
