svenpanne@chromium.org 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%.
