Consolidate code paths evaluating XPath predicates and filters. Don't push context node on stack when evaluating predicates. I have no idea why this was done. It seems completely useless and trying to pop the context node from a corrupted stack has already caused security issues. Filter nodesets in-place and don't create node sets with NULL gaps which allows to simplify merging a great deal. Simply move matched nodes backward and create a compact node set. Merge xmlXPathCompOpEvalPositionalPredicate into xmlXPathCompOpEvalPredicate.
