ager@chromium.org 806c15e4b5 Remove the LookupResult IsValid method because it is confusing.
Replaced IsValid by IsPropertyOrTransition and used IsProperty in most
of the places where IsValid was used before.  Most of the time when
inspecting a lookup result we really want to know if there is a real
property present.  Only for stores are we interested in transitions.
