Fortran: Fix clause splitting for OMP masked taskloop directive

This patch fixes an obvious coding goof that caused all clauses for
the combined OMP masked taskloop directive to be discarded.

	gcc/fortran/
	* trans-openmp.cc (gfc_split_omp_clauses): Fix mask for
	EXEC_OMP_MASKED_TASKLOOP.

	gcc/testsuite/
	* gfortran.dg/gomp/masked-taskloop.f90: New.
