Another untested fix
Unfortunately, the previous patch had problems with debug comparisons.
At the moment I'm bootstrapping the new attached variant which
hopefully does not have this problem and which I'd like to then
submit for 4.8.
In the next stage1 I'd like to go a step further and not mark all
variables as disqualified candidates when analyze_access_trees decides
there are not replacements to be made for them which should make
access structures available to the function modification phase which
then can remove s few more assignments (e.g. to variables or parts of
variables which are never read). But I'm still only experimenting
with that.
