Hello,
this adds the patch
(http://gcc.gnu.org/ml/gcc-patches/2004-05/msg01231.html) that was
ommited in merge due to conflicts.
This patch also makes copy_loop_headers use rewrite_ssa_into_ssa,
which was necessary since with the above change it would be complicated
to use rewrite_out_of_ssa & rewrite_into_ssa together with lno-branch
tree_duplicate_block (that preserves the virtual operands).
