11926e6ecc [gc] Attach page to LocalArrayBufferTracker rather than space
Each local ABT is logically for one page. We passed the space in to the
constructor, but this is wrong because the space a page is in can
change, e.g. for compaction pages.

Instead, pass the page to the local ABT constructor and always get the
space from this. To do this we need to push the AllocateLocalTracker()
helper and friends down to Page, rather than its superclass MemoryChunk.

Unfortunately, we need to keep ReleaseLocalTracker() on MemoryChunk even
though only Pages can have local trackers, because we can't do virtual
dispatch on MemoryChunk::ReleaseAllocatedMemory() which would allow us
to clean up the tracker memory nicely for pages only.

We also have to make sure we update external bytes accounting properly
when swapping spaces, as in SemiSpace::Swap().

aca333123d [heap] Replace retained_size() with ExternalBackingStoreBytes().
ArrayBuffer memory allocated off-heap was previously tracked by a test-
only retained_size() field on each LocalArrayBufferTracker.

Changes in off-heap ArrayBuffer memory usage are now reported to the
Space with which the ArrayBuffer is associated, so that the value is
cheaply available to include in e.g. GC limit calculations, via a new
getter, ExternalBackingStoreBytes().

Changes to external ArrayBuffer backing-store allocations are tracked in
an AtomicNumber associated with each Space, to allow for ArrayBuffers
being concurrently moved or freed from multiple Pages in the same Space
during sweeps & compactions.

b1683f050a [Heap] Fix ArrayBuffer_SemiSpaceCopyMultipleTasks to respect PPC page size
The testcase allocates JSArraybuffer on 2 separate pages which should be
on the New space. In the testcase semi space size is set to 2MB.
Since page size on PPC is 4MB the semi new space size defaults to 4MB.
Therefore when allocating 2nd buffer, scavenge GC kicks in as from-space is
filled up and copies 1st buffer to to-space. Now, the 2nd buffer also gets
allocated on the same to-space, therefore both buffer end up being on the
same page. This fix should allocate enough semi new space to contain 2
pages (for all platform).
The testcase was added as part of https://codereview.chromium.org/2036643002

b2d8bfc793 [heap] Fine-grained JSArrayBuffer tracking
Track based on JSArrayBuffer addresses instead of the attached backing store.
This way we can later on iterate buffers on a single page. The reland also
switches to a page-based implementation where a page contains the set of its
contained (live and dead) buffers.

Details of tracking:
- Scavenge: New space pages are processes in bulk on the main thread
- MC: Unswept pages are processed in bulk in parallel. All other pages
  are processed by the sweeper concurrently.
