	* dwarf2out.c (is_cu_die, is_namespace_die, is_class_die,
	add_AT_pubnames, add_enumerator_pubname, want_pubnames): New functions.
	(comdat_type_struct): New field 'skeleton_die'.
	(breakout_comdat_types): Update it.
	(add_pubname): Rework logic.  Call is_class_die, is_cu_die and
	is_namespace_die.  Fix minor style violation.  Call want_pubnames.
	(add_pubname_string): Call want_pubnames.
	(add_pubtype): Rework logic for calculating type name.  Call
	is_namespace_die.  Call want_pubnames.
	(output_pubnames): Move conditional logic deciding when to produce the
	section from dwarf2out_finish.  Use new skeleton_die field.
	(base_type_die): Call add_pubtype.
	(gen_enumeration_type_die): Unconditionally call add_pubtype.
	(gen_subprogram_die): Adjust calls to add_pubname.
	(gen_namespace_die): Call add_pubname_string.
	(dwarf2out_finish): Call add_AT_pubnames; Move logic on when to
	produce pubnames and pubtypes sections to output_pubnames.
	(common.opt): New option '-gpubnames'.
	(invoke.texi): Document it.
