Andreas Kling acf341862a AK: Remove operators && and || from DistinctNumeric ...

These don't do short-circuit evaluation, and so I ran into some
some very subtle side-effects when converting code to DistinctNumeric.

In code like this:

    MyDistinctNumeric n;
    if (n && check_thing(n))
        return;

There would be no short-circuit evaluation if the return type of
check_thing() was implicitly convertible to MyDistinctNumeric.

Ran into this while making Ext2FS::GroupIndex a DistinctNumeric.
