    Fortran: Fix class dummy-array assignment deep copy [PR110877]

    Recover the class vptr for scalarized elements of nonpointer
    dummy arrays so polymorphic assignment uses the deep-copy path.

            PR fortran/110877

    gcc/fortran/ChangeLog:

            * trans-expr.cc (gfc_trans_assignment_1): Recover the class
            vptr for scalarized elements of nonpointer dummy arrays.

    gcc/testsuite/ChangeLog:

            * gfortran.dg/pr110877.f90: New test.
