cp-tree.h (struct lang_decl): Added field for storing sorted FIELD_DECLs (used in TYPE_DECLs).

	* cp-tree.h (struct lang_decl): Added field for storing sorted
	FIELD_DECLs (used in TYPE_DECLs).
	(DECL_PENDING_INLINE_INFO): Adjusted to use 'u' union.
	(DECL_SORTED_FIELDS): New macro.
	* class.c (method_name_cmp): New function.
	(finish_struct_methods): Modified to support sorting and searching
	methods.
	(finish_struct_anon): Changed code in inner loop to use ELT rather
	than UELT (which required an extra indirection for every reference).
	(field_decl_cmp): New function to support sorting FIELD_DECLs.
	(finish_struct_1): Sort fields.
	* search.c (lookup_field_1): Use DECL_SORTED_FIELDS if we have them.
	(lookup_fnfields_1): Search sorted methods in METHOD_VEC.
	Also, switch to using array indexing rather than a changing pointer.
	* ptree.c (print_lang_decl): Handle TYPE_DECLs that have
	DECL_SORTED_FIELDS.
