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).
