tree.h (struct tree_base): Add nameless_flag bitfield.

	* tree.h (struct tree_base): Add nameless_flag bitfield.
	(TYPE_NAMELESS, DECL_NAMELESS): Define.
	* omp-low.c (create_omp_child_function, scan_omp_parallel,
	scan_omp_task, lower_omp_taskreg): Set DECL_NAMELESS and/or
	DECL_ARTIFICIAL where needed.
	* dwarf2out.c (dwarf2_name): Return NULL if DECL_NAMELESS.
	(type_tag): Return NULL if TYPE_NAMELESS or if TYPE_DECL
	has DECL_NAMELESS set.

	* trans-types.c (gfc_get_array_descriptor_base,
	gfc_get_array_type_bounds): Set TYPE_NAMELESS.
	* trans-decl.c (gfc_build_qualified_array): Set DECL_NAMELESS
	instead of clearing DECL_NAME.
	(gfc_build_dummy_array_decl): Set DECL_NAMELESS.
