* cgraph.h (cgraph_inline_failed_t): Give enum a name

	* lto-cgraph.c (LDPR_NUM_KNOWN): New macro.
	(LTO_cgraph_tags): Add LTO_cgraph_last_tag.
	(lto_output_edge): Use output_enum and var_len_unsigned.
	(lto_output_varpool_node): Likewise.
	(input_overwrite_node): Do not take resolution parameter;
	extract it from a bitpack.
	(input_node): Do not read resolution; use input_enum and
	var_len_unsigned.
	(input_varpool_node): Likewise.
	(input_edge): Likewise.
	(input_cgraph_1): Likewise.
