Subject: 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.
