The debug flag being checked for seems to be controlled by whether the
build is asserts/non-asserts rather than debug/non-debug. Mostly these
correlate, but not necessarily.

As far as I can tell with various combinations of debug/assetions this
change makes no difference on autotools builds, but fixes a check-all
failure with CMake.

This is a follow-up patch for r185524. Being assert enabled does not mean
that DEBUG() is enabled, so we need to check the existence of DEBUG() itself.

Found that having a method to check the strucutre of the followon graph makes
it easy to debug file readers. The method checks if there's no wrong edge in
followOnNexts and followOnRoots. It is called only when debuggging is enabled
for LayoutPass.
