    walk_tree_1: Fix tree-walking of OMP_METADIRECTIVE [PR128001]

    OpenMP's metadirective uses TREE_PURPOSE of TREE_LIST,
    which is not walked by default, leading to a missing
    'omp declare target' attribute.
    Solution: Handle OMP_METADIRECTIVE explicitly.

            PR middle-end/128001

    gcc/ChangeLog:

            * tree.cc (walk_tree_1): Add comment; handle
            OMP_METADIRECTIVE explicitly.

    gcc/testsuite/ChangeLog:

            * gfortran.dg/gomp/metadirective-14.f90: New test.
