[CSA][cleanup] TNodify some methods related to prototype and property lookup

Browse Source 
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.
