4ef84b9240 Add a ResourceConstraint for the embedder to specify that V8 is running on a memory constrained device.
This enables us to specialize certain operations such that we limit memory
usage on low-memory devices, without reducing performance on devices which
are not memory constrained.

1083d1f817 Remove deprecated profiler API
This change removes --prof-lazy command line flag that was introduced for the old CPU profiler implementation in Chrome DevTools. DevTools now use profiler API defined in v8-profiler.h

This change also removes methods for pausing resuming --prof profiler. These methods were deprecated in v.3.20 (https://code.google.com/p/v8/source/browse/branches/3.20/include/v8.h#4629)

After this change the profiler will always start if --prof option is passed and can be stopped either in the tests or if write to log file fails.

7a2c253e24 Move OS/compiler/feature detection to public v8config.h header.
From now on the v8config.h header should be the one and
only file where we do (freaky) checks to detect OS, C++
compiler or certain compiler features. Since we need that
both internally and for the public API, the new v8config.h
is the proper place to add (everything is prefixed with V8_
so we are safe).

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.

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.

97409c2363 Move InitializeICU() to the V8 API and use it.
I can't get rid of the enable_i18n flag yet, as we need to be able to
turn off all extensions for creating the snapshot.

67d9051bcd Create AllocationSite objects, pointed to by AllocationSiteInfo.
This creates a platform where we can do additional things with allocation sites,
other than just aid in reducing array transitions.

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.

de07db147f Ensure CheckInitialized is present independent of define.
This makes sure that the same symbols are present, independent of which
defines have been used while building V8. Otherwise only embedders with
compatible defines would be able to link against that binary.
