    OpenACC: Fix reduction tree-sharing issue [PR106982]

    The tree for var == incoming == outgound was
    'MEM <double[5]> [(double *)&reduced]' which caused the ICE
    "incorrect sharing of tree nodes".

            PR middle-end/106982

    gcc/ChangeLog:

            * omp-low.cc (lower_oacc_reductions): Add some unshare_expr.

    gcc/testsuite/ChangeLog:

            * c-c++-common/goacc/reduction-7.c: New test.
            * c-c++-common/goacc/reduction-8.c: New test.

    (cherry picked from commit d3df98807b58df186061ad52ff87cc09ba593e9b)
