re PR fortran/48894 (generic omp_get_ancestor_thread_num(l(i)) produces incorrect...

	PR fortran/48894
	* fortran.c: Include limits.h.
	(TO_INT): Define.
	(omp_set_dynamic_8_, omp_set_num_threads_8_): Use !!*set instead of
	*set.
	(omp_set_num_threads_8_, omp_set_schedule_8_,
	omp_set_max_active_levels_8_, omp_get_ancestor_thread_num_8_,
	omp_get_team_size_8_): Use TO_INT macro.
	* testsuite/libgomp.fortran/pr48894.f90: New test.
