Original commit message:
api: introduce SealHandleScope
When debugging Handle leaks in io.js we found it very convenient to be
able to Seal some specific (root in our case) scope to prevent Handle
allocations in it, and easily find leakage.

Should help us identify and fix Handle leaks in core and user-space code.
NOTE: Works only in Debug build now, but is still better than nothing.

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.)

clang++ on FreeBSD was blaming v8 for using invalid casts from nullptr:
reinterpret_cast from 'nullptr_t' to '...' is not allowed
Replace casts with NULL, or NULL with 0 where applicable.

This commit upgrades V8 from 3.31.74.1 to 4.1.0.7. Despite the major
version bump, there are no API or ABI changes, it's a bug fix release
only.

Fix double definition errors in the libv8_base.a library target by
compiling out stub functions when building for x32.
This fix is incomplete because, although V8 now builds, it makes a
number of bad assumptions about the size of stack slots, see
https://code.google.com/p/v8/issues/detail?id=3630.

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.

fd80a31e06 has introduced a segfault
during redundant boundary check elimination (#8208).
The problem consists of two parts:
1. Abscense of instruction iterator in
`EliminateRedundantBoundsChecks`. It was present in recent v8, but
wasn't considered important at the time of backport. However, since
the function is changing instructions order in block, it is
important to not rely at `i->next()` at the end of the loop.
2. Too strict ASSERT in `MoveIndexIfNecessary`. It is essentially a
backport of a45c96ab from v8's upstream. See
https://github.com/v8/v8/commit/a45c96ab for details.
