Original commit message:
TypedArray accessor detection: consider entire prototype chain
When looking up a special accessor for known TypedArray fields
("length", "byteLength", "byteOffset"), consider the entire
prototype chain, not only the direct prototype.
This allows subclasses of TypedArrays to benefit from fast
specialized accesses.

Improvement depends on the code, but generally brings us back to the
performance that we had before the v8 update (if not making it
faster).

Original commit message:
heap: make array buffer maps disjoint
Remove intersection from the `std::map`s representing current live
ArrayBuffers. While being simpler to understand, it poses
significant performance issue for the active ArrayBuffer users (like
node.js).
Store buffers separately, and process them together during
mark-sweep phase.
The results of benchmarks are:
$ ./node-slow bench && ./node-fast bench
4997.4 ns/op
4685.7 ns/op
NOTE: `fast` - was a patched node.js, `slow` - unpatched node.js
with vanilla v8.

Upgrade the bundled V8 and update code in src/ and lib/ to the new API.
Notable backwards incompatible changes are the removal of the smalloc
module and dropped support for CESU-8 decoding. CESU-8 support can be
brought back if necessary by doing UTF-8 decoding ourselves.
This commit includes https://codereview.chromium.org/1192973004 to fix

Use optparse in js2c.py for python compatibility
Without this change, V8 won't build on RHEL/CentOS 6 because the
distro python is too old to know about the argparse module.

Undo the ABI (but not API) change to NamedPropertyHandlerConfiguration.
This avoids a NODE_MODULE_VERSION bump and forcing everyone to recompile
their add-ons, at the cost of increasing the delta with upstream V8.
This commit effectively backs out 4.1.0.16, the release that introduced
the ABI change (and nothing else.)

V8 3.26.31 has received 14 patches since the upgrade to 3.26.33. Since
3.26.33 is technically a tag on the 3.27 branch, reverting back to
3.26.31 would remove now default functionality like WeakMaps. Because of
that the patches have simply been cherry-picked and squashed.
Here is a summary of all patches:
* Fix index register assignment in LoadFieldByIndex for arm, arm64, and
mips.
* Fix invalid attributes when generalizing because of incompatible map
change.
* Skip write barriers when updating the weak hash table.
* MIPS: Avoid HeapObject check in HStoreNamedField.
* Do GC if CodeRange fails to allocate a block.
* Array.concat: properly go to dictionary mode when required.
* Keep CodeRange::current_allocation_block_index_ in range.
* Grow heap slower if GC freed many global handles.
* Do not eliminate bounds checks for "<const> - x".
* Add missing map check to optimized f.apply(...).
* In GrowMode, force the value to the right representation to avoid
deopts between storing the length and storing the value.
* Reduce max executable size limit.
* Fix invalid condition in check elimination effects.
* Fix off-by-one error in Array.concat slow mode check.
