(Flength, Felt, Ffillarray): Remove loop around wrong_type_argument.
(Fcopy_sequence, concat): Cleanup wrong_type_argument use. (concat): Use CHECK_NUMBER. (Felt): Use CHECK_ARRAY. (Fsubstring, substring_both): Use CHECK_VECTOR_OR_STRING. (Fmemq): Use CHECK_LIST. (Fassq, Fassoc, Frassq, Frassoc): Use CAR. (assq_no_quit): Use CAR_SAFE. (Fnthcdr, Fmember, Fdelq, Fdelete, Fnreverse, Fnconc): Use CHECK_LIST_CONS. (Freverse, Fplist_get, Flax_plist_get): Use CHECK_LIST_END.
