Remove CHECK_FIXNUM_CAR etc.

* src/coding.c (CHECK_FIXNAT_CAR, CHECK_FIXNAT_CDR):
* src/lisp.h (CHECK_FIXNUM_CAR, CHECK_FIXNUM_CDR):
Remove.  All uses removed.  These seem to have been based on
the assumption that the argument cons needs to be modified,
an assumption that is incorrect for fixnums.
(Fdefine_coding_system_internal): Use CHECK_RANGED_INTEGER
instead of a special diagnostic for graphic register numbers.
