Elaborate "info record".
	* record.c (struct record_end_entry): New field 'insn_num'.
	(record_insn_count): New variable.
	(record_open): Initialize record_insn_count.
	(info_record_command): Display contents of record log as
	lowest, current, and highest instruction counts.
	(show_record_insn_number): Delete.
	(_initialize_record): Remove add_cmd show_record_insn_number.
