	Add process record Linux system call 64 bits support.

        * linux-record.h (linux_record_tdep): Add size_pointer,
        size_size_t, size_iovec and arg6.  Change the values of
	size_int, size_long and size_ulong to
	gdbarch_int_bit (gdbarch) / TARGET_CHAR_BIT,
	gdbarch_long_bit (gdbarch) / TARGET_CHAR_BIT,
	gdbarch_long_bit (gdbarch) / TARGET_CHAR_BIT.
	* i386-linux-tdep.c (i386_linux_init_abi): Ditto.
	(i386_linux_intx80_sysenter_record): Add a check for system
	call number.
        * linux-record.c (record_linux_system_call): Make this
        function support 64 bits.
