[Bug fortran/24524] New: Fortran dependency checking should reverse loops

[pinskia at gcc dot gnu dot org]

program testcase_fold
  real, dimension(:), pointer :: mystruct
  mystruct(1:3) = mystruct(2:4)
END Program testcase_fold

That loop should be transvered in reverse oder so that we don't need a
temporary array.
