Refactor and fix typo in CHECK_*_COERCE_MARKER

* src/data.c (check_integer_coerce_marker)
(check_number_coerce_marker): New functions.
Also, fix a typo in the former, by having it use
Qinteger_or_marker_p not Qnumber_or_marker_p.
(arithcompare, floatop_arith_driver, bignum_arith_driver)
(arith_driver, Fplus, Fminus, Ftimes, Fquo, Frem, Fmod)
(minmax_driver, Flogand, Flogior, Flogxor, Fadd1, Fsub1):
Use them in place of the similarly-named macros.
* src/lisp.h (CHECK_NUMBER_COERCE_MARKER)
(CHECK_INTEGER_COERCE_MARKER): Remove; no longer used.
