At least it seems to do the same thing up to -fdump-tree-optimized. So the
problem appears from here to the assembly code!-(I won't comment about the
missing controls after ~30 flags;-).
Note that the failures disappear with -m64 (missing/bad conversion).

I have reverted revisions 130039, 130045, 130067, and 130072, and I have also
done a clean bootstrap without changes.
