[Bug optimization/14562] [tree-ssa] Incorrect loop code caused by copyrename

Actually the PHI functions from tree copy header are fine, the real issue is that copyrename is renaming
a variable to one which is set also through the loop.
I found this seeing that copyrename2 was messing up the trees.
