Bug 54524 - Allow JSObject to fully utilize cell's capacity for inline storage.
Currently JSObject is both directly instantiated for regular JS objects, and
derived to implement subtypes. A consequence of this is that we need to ensure
that sufficient space from the cell is left unused and available for any data
members that will be introduced by subclasses of JSObject. By restructuring
the internal storage array out of JSObject we can increase the size in the
internal storage for regular objects.
Add classes JSFinalObject and JSNonFinalObject. JSNonFinalObject retains as
much additional capacity as is currently available to allow for data members
in subclasses. JSFinalObject utilizes all available space for internal storage,
and only allows construction through JSFinalObject::create().
The additional storage made available in the JSObject means that we need no
longer rely on a union of the internal storage with a pointer to storage that
is only valid for external storage. This means we can go back to always having
a valid pointer to property storage, regardless of whether this is internal or
external. This simplifies some cases of access to the array from C code, and
significantly simplifies JIT access, since repatching no longer needs to be
able to change between a load of the storage pointer / a LEA of the internal
storage.

In strict mode the optimisation that we use to skip a lookup
on the global object is incorrect and lead to us always
disallowing global writes when we needed to do a dynamic slot
lookup. Now the strict mode path actually checks for the
property.

Refactor handles and weak pointers to become nicer and more automatic
https://bugs.webkit.org/show_bug.cgi?id=54415
Move to a true handle based mechanism for GC value protection. This
also allows us to switch to a more sensible behaviour for weak pointers
in which weak pointers are automatically updated.
This allows us to remove the old (and convoluted) that required all
objects that may be held by a weak reference to be aware of the reference
and manually clear them in their destructors.
This also adds a few new data types to JSC that we use to efficiently
allocate and return the underlying handle storage.
This patch is largely renaming and removing now unnecessary destructors
from objects.

<rdar://problem/8805364> Malloc zone enumeration code should be safe in the face of errors from the memory reader.
* wtf/FastMalloc.cpp:
(WTF::PageHeapAllocator::recordAdministrativeRegions): Use the new helper function to walk the linked list safely.
(WTF::TCMalloc_ThreadCache_FreeList::enumerateFreeObjects): Ditto.
(WTF::TCMalloc_Central_FreeList::enumerateFreeObjects): Ditto.
(WTF::TCMallocStats::PageMapFreeObjectFinder::visit): Bail out if the span could not be read.
(WTF::TCMallocStats::PageMapMemoryUsageRecorder::visit): Ditto.
* wtf/MallocZoneSupport.h:
(WTF::RemoteMemoryReader::operator()): Remove an assert that is not valid.
(WTF::RemoteMemoryReader::nextEntryInLinkedList): Add a helper function for retrieving the next entry in
a linked list. It maps a failed read of the remote memory in to a null pointer, which all callers can
handle gracefully.

Bug 54164 - Optimize global_var accesses on JSVALUE64
Directly embed the pointer to d->registers, optimize out the load
from the variable object, as we do already in JSVALUE32_64.
This is a ~1.5% win on sunspidey.
