The problem in this PR is, that the structure we mess up points-to info has no
fields in its lower half, but only two varinfos (D.2860, offset 128 size 64
and D.2860.visited_, offset 192 size 64 -- the first one is actually
D.2860.func_ptr_, but we name the first after the decl always).  Now, there
_is_
a structure at offset zero, D.2857 (size 192), which contains D.2860.func_ptr_.

So we fail to have a varinfo for the offset the expression &D.2860.D.2857
points
to and we loose the first varinfo wrongly during the &this_18->functor_
addition of 64.

Now, either we need to generate fake varinfos for the 'holes' we end up with,
or just punt here.
