    tree-optimization/107865 - ICE with outlining of loops

    The following makes sure to clear loops number of iterations when
    outlining them as part of a SESE region as can happen with
    auto-parallelization.  The referenced SSA names become stale otherwise.

            PR tree-optimization/107865
            * tree-cfg.cc (move_sese_region_to_fn): Free the number of
            iterations of moved loops.

            * gfortran.dg/graphite/pr107865.f90: New testcase.
