Log:
    PR fortran/49792
    * trans-expr.c (gfc_trans_assignment_1): Set OMPWS_SCALARIZER_WS
    bit in ompws_flags only if loop.temp_ss is NULL, and clear it if
    lhs needs reallocation.
    * trans-openmp.c (gfc_trans_omp_workshare): Don't return early if
    code is NULL, emit a barrier if workshare emitted no code at all
    and NOWAIT clause isn't present.

    * testsuite/libgomp.fortran/pr49792-1.f90: New test.
    * testsuite/libgomp.fortran/pr49792-2.f90: New test.
