re PR fortran/49792 (OpenMP workshare: Wrong result with array assignment)
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.
