3b5a6ef2e7 Removing LookupTransition from LookupRealNamedProperty and related utility functions. 
Callsites now have to manually lookup transitions if required. This
avoids unnecessary overhead of looking up transitions when we don't need
them. This also allows us to use IsFound() in many places where
IsProperty() was required previously.

11e5c9e281 Removed transitions from the accessor pair descriptors. 
AccessorPair related transitions are now also stored as single map links, simplifying the code that handles transitions. AccessorPairs can now be shared between descriptor arrays, since they can only be mutated after another transition anyway; during which the pair is copied before writing.

65e7a14973 Handle setters on the prototype chain efficiently by default. 
Note that changes on the prototype chain should already be handled by
StubCompiler::CheckPrototypes, if not, it is a bug there and not in
LookupForWrite. Furthermore, neither test262 nor WebKit layout tests hint at a
compability issue, so it should be safe to remove a redundant check.

The good point about this CL: It improves Box2D's performance by 22%.

The LastAdded points to the descriptor that was last added to the array. From the descriptor we can deduce the NextEnumerationIndex. This allows us to quickly find the property that we are transitioning to, which is necessary for transition-intensive code, eg JSON parsing.
