Yes, I've merged the fix from MySQL-5.5

As you like.
If I recall correctly, it marks Item_nodesets as always not const.
I don't see it causing any harm, these items are never part of the
item tree, so their non-const-ness cannot be propagated up and affect
other items and complex expression. But I could be missing something,
sure.
