XPath: Fix optimization bug with //name[last()]
The actual condition for the optimization is invariance from context list
-- this includes both position() and last().
Instead of splitting the posinv concept just include last() into
non-posinv expressions - this requires sorting for boolean predicates that
depend on last() and do not depend on position(). These cases should be
very rare.
