Reorganize hot/cold output to allow atoms to be properly detected.


This is a proof-of-principle patch that reorganizes the output of the hot/cold
partitions so that section switches are only made when needed.  Although it was
done to make the atom detection work with ld64, IMO - it makes the asm more
readable for linux too... but that's a side-effect of course.

This is a very invasive patch, because it touches debug output - so some way to
test more widely would be needed.  However, worth testing as a resolution for
this problem.
