Log message:
	Friend class name lookup 5/n
	PR c++/1016
	* cp-tree.h (pushtag): Adjust declaration.
	* decl.c (lookup_and_check_tag): Call lookup_type_scope if
	lookup_name fails.

	(start_enum): Adjust call to pushtag.
	* name-lookup.c (ambiguous_decl): Ignore hidden names.
	(qualify_lookup): Change return type to bool.
	(hidden_name_p): New function.

	(lookup_type_scope): Update comments.
	(maybe_process_template_type_declaration): Change parameter name
	from globalize to is_friend.
	(pushtag): Change globalize parameter of type int to tag_scope.
	Hide name if introduced by friend declaration.
	* name-lookup.h (hidden_name_p): Add declaration.
	* parser.c (cp_parser_lookup_name): Don't deal with hidden name
	here.
