Bugs fixed:
* v0.12 and later: in-object properties not printing correctly.
* 64-bit: not printing external strings correctly (offset was hardcoded
for 32-bit). This would happen with "::jsstack -vn0" because the
script "node.js" wasn't printed correctly, at least with 0.10 core
files.
* 64-bit: printing JS source (via "::jsstack -v") emits errors and shows
the wrong code.
* Several build warnings.
* Two-byte strings are unnecessarily truncated.
* Could print friendlier note when given obviously bogus function token
positions.
New features:
* ::jsstack prints much cleaner output by default.
* ::jsprint keys are now quoted.
* ::jsstack -v includes "this" value for each function on the stack.
* ::jsstack -v includes more details about each argument (constructor
names for each object).
* new commands: ::jsconstructor, ::jsfunctions, ::jssource, ::nodebuffer
and ::v8internal.
* ::findjsobjects and ::jsprint hidden flags for developers to measure
and improve test coverage.
* internal jsobj_properties() function is much better documented.

Building node with GCC > 4.4 on CentOS makes the node binary depend on a
more recent version of the C/C++ runtime that is not installed by
default on these older CentOS platforms, and probably on other platforms
as well.
Building node with the default gcc and g++ compilers that come with
these older versions of CentOS allows to ship a node binary that runs
out of the box on these setups with older C/C++ runtimes.
This change works around a bug that was fixed in GCC 4.5. Versions of
GCC < 4.5 would not support using the injected-class-name of a
template base class as a type name.
This change also disables aliasing optimizations for toolchains using
GCC <= 4.4 as they're not able to deal with the aliasing in the queue
implementation used by libuv and node (see src/queue.h).

This reverts commit 45f1330425.
45f1330425 was basically breaking
node-inspector. V8 landed a patch upstream that would probably fix these
issues (see https://codereview.chromium.org/813873007), but without the
ability to properly test it in the wild, it's safer to just revert the
breaking change.
Fixes#8948.

Reduce the overhead of the CPU profiler by replacing sched_yield() with
nanosleep() in V8's tick event processor thread. The former only yields
the CPU when there is another process scheduled on the same CPU.
Before this commit, the thread would effectively busy loop and consume
100% CPU time. By forcing a one nanosecond sleep period rounded up to
the task scheduler's granularity (about 50 us on Linux), CPU usage for
the processor thread now hovers around 10-20% for a busy application.

The latest merge resulted in uv__loop_configure being defined twice on

Original commit message:
Fix Unhandled ReferenceError in debug-debugger.js
This fixes following exception in Sky on attempt to set a breakpoint
"Unhandled: Uncaught ReferenceError: break_point is not defined"
I think this happens in Sky but not in Chrome because Sky scripts are executed in strict mode.

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.
