bmeurer a0484bc611 [compiler] Properly guard the speculative optimizations for instanceof. ... Add a general feedback slot for instanceof similar to what we already have for for-in, which basically has a fast (indicated by the uninitialized sentinel) and a slow (indicated by the megamorphic sentinel) mode. Now we can only take the fast path when the feedback slot says it hasn't seen any funky inputs and nothing funky appeared in the prototype chain. In the TurboFan code we also deoptimize whenever we see a funky object (i.e. a proxy or an object that requires access checks) in the prototype chain (similar to what Crankshaft already did). Drive-by-fix: Also make Crankshaft respect the mode and therefore address the deopt loop in Crankshaft around instanceof. We might want to introduce an InstanceOfIC mechanism at some point and track the map of the right-hand side.
