Performs a logical <b>XOR</b> of this bit set with the bit set
argument. This bit set is modified so that a bit in it has the
value {@code true} if and only if one of the following
statements holds:
<ul>
<li>The bit initially has the value {@code true}, and the
corresponding bit in the argument has the value {@code false}.
<li>The bit initially has the value {@code false}, and the
corresponding bit in the argument has the value {@code true}.
</ul>
