d208eea478 Speed-up 'new TypedArray(arrayLike)'. 
Handle specially the cases when the argument is a typed array,
in particular of the same type as the one we create.

Allocate backing store uninitialized in cases when we can guarantee
complete initialization.

e53471dbaa Remove elements transitions from the transition array. 
This is preparatory work for reordering the transition tree. Since elements transitions will be at the root of the transition tree, runtime access to them is slow since we have to walk the transition tree backwards first. Hence remove the optimization that promoted them to a special field, requiring a pointer (mostly NULL) in every non-simple transition array.

96fc677d25 Pipe a script's CORS status through V8 during compilation. 
In order to properly sanitize exception data during a 'window.onerror'
handler, we need to know whether a script was served with proper CORS
headers at the time it was loaded into V8. This patch adds a single bool
to ScriptOrigin, and pipes that through the compiler to land on the
Script object. We can then retrieve the parameter when calling the
embedder's exception callback.

0826f85a02 Put object templates of the i18n extension on the heap object. 
Using function local statics doesn't work, as we need the templates per
isolate.

I'm not #ifdef'ing the definitions out, because kEmptyStringRootIndex
changes depending on whether the two additional slots are present or
not.

682a0d65c6 Deprecate v8::V8::Pause/ResumeProfiler 
The methods were added to the public API in r1185 when Chrome DevTools were using the same output as produced for tick processor when --prof option is specified.

I don't see any existing clients of these methods and since they add a noticeable complexity to the profiler code I'd like to remove them.

625a0e9759 Add map transition for observed objects 
This patch enables objects to undergo a single transition when they become observed, avoiding the need to create a new map for every observed objects.

Observed objects which become unobserved does not cause another map transition and unobserved does not clear the observed bit on the map. The unobserved object.

7e0ee5301e Add internal fields to JSArrayBufferViews (JSTypedArray and JSDataView) 
In Blink, JSTypedArray and JSDataView objects act as "wrappers" for C++
objects. Wrapping protocol in Blink requires all wrapper JavaScript objects
to have a certain amount of internal fields that Blink uses for
book-keeping (essentially a pointer to C++ object and some type
information). This change adds those internal fields to JSTypedArray and
JSDataView, in a similiar way to how it is done for JSArrayBuffer.

0ac0edb707 Test that profiler is stopped when isolate is being disposed 
The only way to get v8::CpuProfiler instance in the V8 public API is to call v8::Iolate::GetCpuProfiler(). The method will return NULL if the isolate has not been initialized yet or has been torn down already. It is the client's reponsibility to make sure that CPU profiling has been stopped before disposing of the isolate.

This CL adds a test for this and several ASSRTS enforcing that assumptions. This allowed to be sure that heap is always setup when CPU profiling is being started. Based on that the number of places where already compiled functions are reported to the profiler event processor boils down to the single place (CpuProfiler::StartProcessorIfNotStarted). I'm going to rely on this assumption in further changes.

36e91242fd Make Object.freeze fast 
This patch both speeds up the freeze operation itself, but also
allows properties to remain in fast mode. Objects with non-empty
elements backing stores still end up with slow elements.

Relanding r14758 and r14759 with fix for Test262: only mark properties
and elements READ_ONLY if they are not JS setter/getters. Tightened up
tests to assert frozen-ness, and added targeted tests for the new code
(covering accessors).

cfe3e039ca Don't use anonymous types declared in an anonymous union. 
They are a non-standard extension (probably in C1X, IIRC), but clang is unhappy
with them when -Wnested-anon-types is enabled, which seems to be implied by
-pedantic.

With this change and the previous fix for clang, we are now -Werror clean, even
on clang 3.3.

3f09e0a3d8 Remove separate maps for function instances 
ES3 specified that functions created via Function() would have
enumerable prototypes, unlike function literals.  For this reason, V8
has always had two prototypes for functions: "function_map" for
literals, and "function_instance_map" for "function instances": those
functions created by Function().

However, since 2009 or so, both maps have been the same!  Both have had
writable, non-enumerable prototypes.  Moreover, ES5 changed to specify
that function instances would have non-enumerable prototypes.

This patch removes the separate maps for function instances in sloppy
and strict mode.

7ed7af2f9f Tell the GC prologues to construct RetainedObjectInfos only when needed. 
The GC prologue is called by the GC, but also by the heap snapshotter. The
RetainedObjectInfos are only needed by the heap snapshotter, so it's wasteful to
construct them always. (And it will be even more wasteful when Blink migrates to
the new GC APIs, since after that point it no longer knows about object groups.)

061f523b5a Change cctest/test-lockers to not copy persistent handles around. 
Instead, create Local handles to pass them around. This also means that the
code needs to be shifted around a bit such that a handle scope exists when
creating threads.
