Fix Issue 20743 - Checked!(int, Abort) does not abort but raise SIGFPE

[wolframw]

The necessity for this is due to an x86 design idiosyncrasy. If an integer division causes an overflow, a division error occurs, causing SIGFPE to be raised on POSIX systems and the SEH exception EXCEPTION_INT_OVERFLOW to be thrown on Windows. Since the Warn hook performs the offending calculation nevertheless, a special case is added such that an overflowing division is not performed.
