This change relands the last part of https://crrev.com/c/2601880 . ScopeInfo has a vestigial 'length' field from when it used to be a FixedArray. This change removes that field, which saves some memory. More specifically: - Make ScopeInfo inherit from HeapObject, not FixedArrayBase which supplied the 'length' field. - Change FactoryBase::NewScopeInfo to allocate the updated object shape. It maintains the existing behavior of filling the newly-allocated object with undefined, even though that's not a valid ScopeInfo and further initialization is required. - Change a few length computations to use HeapObject::kHeaderSize rather than FixedArray::kHeaderSize. - Remove an unnecessary heap verifier function.

Rather than doing a set lookup for each bytecode offset during iteration, rely on the fact that bytecode offsets are monotonically increasing, and store the handler offsets in a sorted array with a "next offset" cursor that the iteration can increment when a handler is found.

This CL is part of a series that makes SwissNameDictionary available as a new property backing store. Previously, the flag v8_dict_mode_prototypes allows selecting between NameDictionary and OrderedNameDictionary as the backing store used for all dictionary mode objects. This series of CLs changes this such that enabling the flag causes SwissNameDictionary being used instead of OrderedNameDictionary. The behavior for when the flag is not set remains unchanged (= use NameDictionary). This particular CL just collects many small changes, including some CSA changes where runtime calls are necessary.

We sometimes have a need to check for termination requests while we're in the middle of non-GC-safe computations, so we can't do a full "HandleInterrupts" (which could do GC).

If a method happens on the main thread and only on the main thread (i.e. it will never be run on the background), it is safer to use non-atomic accessors as TSAN will give warnings if we use them improperly. As a drive-by, pass the isolate as a parameter where it was readily available as it saves us from getting the isolate from the object later on.
