i386: Remove ndd support for *add<mode>_4 [PR113744]

*add<mode>_4 and *adddi_4 are for shorter opcode from cmp to
inc/dec or add $128. But NDD code is longer than the cmp code,
so there is no need to support ndd.

gcc/ChangeLog:

PR target/113744
* config/i386/i386.md (*add<mode>_4): Remove ndd support.
(*adddi_4): Ditto.
