With bytecode flushing and lazy feedback allocation, we need to call
%PrepareForOptimization before we call %OptimizeFunctionOnNextCall,
ideally after declaring the function.

The KeyedStoreMode that we get out of the FeedbackNexus doesn't
necessarily need to apply when we have "static knowledge" about
the receiver, i.e. when the receiver is a known JSTypedArray, but
the KEYED_STORE_IC has seen only JSArray instances so far. The
DCHECK was too restrictive in this case, since we can just ignore
the KEYED_STORE_IC mode (like we ignore the maps).
