Andreas T Jonsson f6f75112d7 refactor: cleanup phase 4 -- width-generic div.c ...

cord8/cord16 unified into one CORD_DEFINE X-macro template with two
instantiations; the rewrite also eliminates the do-nothing else
branches and redundant temporaries from the CORD loops.

negate8/negate16 unified into cord_negate() (width-mask
parameterized); POSTIDIV factored into v20_divide_error_flags() and
postidiv_fix_signs(). The four DIV/IDIV exec handlers are generated
from EXEC_DIV_DEFINE/EXEC_IDIV_DEFINE templates. Magic cycle costs
(80/101/144/165) are named constants.

div.c: 477 -> 291 lines. Verified flag- and cycle-exact against all
635 MOO test files (8088 + V20).
