re PR fortran/27395 (Problem with arrays in the OpenMP REDUCTION clause in Fortran) 

PR fortran/27395
	* gimplify.c (gimplify_scan_omp_clauses): Compare OMP_CLAUSE_CODE
	rather than TREE_CODE to OMP_CLAUSE_REDUCTION.  Set also GOVD_SEEN
	bit for OMP_CLAUSE_REDUCTION_PLACEHOLDER.

	* testsuite/libgomp.fortran/pr27395-1.f90: New test.
