Original change's description:
> [CSA][cleanup] TNodify some methods related to prototype and property lookup
>
> This is a CL in a string of CLs that aims to TNodify CSA. In particular,
> there were some loads that were done in AnyTagged instead of
> TaggedPointer. TNode-ifying them brings improvement in pointer
> compression since we are able to decompress using the Pointer
> decompression.
>
> TNodified:
> * LoadJSFunctionPrototype
> * TryPrototypeChainLookup
> * OrdinaryHasInstance
>
> Also TNodified loads regarding:
> * FeedbackCell::kValueOffset
> * HeapObject::kMapOffset
> * JSFunction::kSharedFunctionInfoOffset
> * JSFunction::kFeedbackCellOffset
> * Map::kInstanceTypeOffset
> * Map::kInstanceDescriptorsOffset
> * Map::kPrototypeOffset
>
> Drive-by cleanup: StoreJSArrayLength and StoreElements were unused.
