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. git-svn-id: https://pugixml.googlecode.com/svn/trunk@1060 99668b35-9821-0410-8761-19e4c4f06640
