529f801fde Adapt Danno's Track Allocation Info idea to fast literals. When allocating a literal array, 
we store an AllocationSiteInfo object right after the JSArray, with a pointer to the
boilerplate object. Later, if the array transitions we check for the continued existence
of the temporary AllocationSiteInfo object (has no roots). If found, we'll use it to
transition the boilerplate array as well.

4cd41edcd9 Add methods to allow resuming execution after calling TerminateExecution(). 
Two new methods are added to allow embedders to determine that execution
should be resumed at a particular point in the stack without being forced
to unwind all JS frames.

* V8::ResumeExecution() -- When execution is terminated via a call to
  V8::TerminateExecution(), this method can be called to clear the
  termination exception so that the engine can continue to be used.

* TryCatch::HasTerminated() -- When a TryCatch has caught a termination
  exception, HasTerminated() will return true to indicate it is valid to
  call V8::ResumeExecution() if desired.

A test case is added to cctest/test-thread-termination.cc.

c54fc70f13 Store Object.observe state per-isolate rather than per-context 
This requires adding a new JSObject to the strong root list and populating it from
object-observe.js. The main other change is that we now directly use ObjectHashTable
from JS rather than using WeakMap, since using the latter would end up leaking whichever
Context initialized that observation state.

Added a test via the API showing that different contexts all end up working on the same state.

f3807ca17b Heavy cleanup of the external pointer API. 
Added highly efficient Object::SetAlignedPointerInInternalField and
Object::GetAlignedPointerFromInternalField functions for 2-byte-aligned
pointers. Their non-aligned counterparts Object::GetPointerFromInternalField and
Object::SetPointerInInternalField are now deprecated utility functions.

External is now a true Value again, with New/Value/Cast using a JSObject with an
internal field containing a Foreign. External::Wrap, and External::Unwrap are now
deprecated utility functions.

Added Context::GetEmbedderData and Context::SetEmbedderData. Deprecated
Context::GetData and Context::SetData, these are now only wrappers to access
internal field 0.

Added highly efficient Context::SetAlignedPointerInEmbedderData and
Context::GetAlignedPointerFromEmbedderData functions for 2-byte-aligned
pointers.

37759f4d64 Implement committed physical memory stats for Linux. 
The patch introduces CommittedPhysicalMemory function to
the Heap class that reports committed *physical* memory acquired
for the heap from the OS.
It is important because some OSes may defer actual committment on e.g.
first access to the region.
So reporting just plain committed size led to various weird artifacts
like showing V8 allocated memory higher than the whole process
private size.

9dc2c5b83d Add an API for enumerating persistent handles 
This API lets the embedder enumerate handles that have class ids. WebKit will
use this feature during garbage collection to compute object groups for DOM
nodes. Previously, we kept a list of DOM nodes on the WebKit side, but that
list is redundant with the global handles list in V8.

b10d5d7f08 Deoptimization support for accessors. 
Highlights of this CL:

 * Introduced a new opcode in the deoptimizer for a setter stub frame.

 * Added a global setter stub for returning after deoptimizing a setter.

 * We do not need special deopt support for getters, although the getter stub creates an internal frame. The normal machinery works just right for this case, although we generate a stack that can never occur during normal fullcode execution. If this hurts us one day, we can parameterize and reuse the setter deopt machinery.

1336b913d0 Make built-ins strict mode conforming, and support a --use-strict flag. 
* Turned all uses of 'const' into 'var'.
* Turned all uses of local 'function' into 'var'.
* Added a couple of missing toplevel 'var' declarations.

One consequence is that the properties on the builtin object  are no longer
non-writable, and I had to adapt one test. Is that a problem?

Unfortunately, we cannot actually switch the library scripts to strict mode
by default, because that makes observable things like poisoned .caller properties
for library functions.

This shaves 416+ KB, just under 1% off the size of the debug d8 executable
on Linux (mostly because the CheckHelper functions for assertions were
getting separate copies for each compilation unit).  The difference in
release builds is negligible---a size reduction of 0.1%.

Also, change namespace-level 'static const' variables to remove the static
storage class as it's the default.

fdade92c20 Reorganize object type enum, such that proxies are no longer in the middle 
of the range of proper JS objects.

Unfortunately, callable types no longer form a range now. However, there
are only two anyway. We put them at either end of the range of JS object
types so that certain compares can be combined.

2) Don't generate a call to a stub while generating a stub, unless we can be
sure that the stub we are calling has already been generated (the stub
generation code is not reentrant wrt. GC).

615add8463 Expose APIs for detecting boxed primitives, native errors and Math. 
While implementing structured clone I found that I need support
for detecting and creating objects using the builtin Number, String
and Boolean constructors; this CL adds this support. I also need
to be able to detect entities of "native object type (e.g., Error)",
hence the new IsNativeError() calls.

508b22c436 "Deiceolate" Thread classes. 
Thread class was receiving an isolate parameter by default.
This approact violates the assumption that only VM threads
can have an associated isolate, and can lead to troubles,
because accessing the same isolate from different threads
leads to race conditions.

This was found by investigating mysterious failures of the
CPU profiler layout test on Linux Chromium. As almost all
threads were associated with some isolate, the sampler was
trying to sample them.

As a side effect, we have also fixed the DebuggerAgent test.

Thanks to Vitaly for help in fixing isolates handling!

670f947a5c Implement set trap for proxies, and revamp class hierarchy in preparation: 
- Introduce a class JSReceiver, that is a common superclass of JSObject and
  JSProxy. Use JSReceiver where appropriate (probably lots of places that we
  still have to migrate, but we will find those later with proxy test suite).

- Move appropriate methods to JSReceiver class (SetProperty,
  GetPropertyAttribute, Get/SetPrototype, Lookup, and so on).

- Introduce new JSFunctionProxy subclass of JSProxy. Currently only a stub.

- Overhaul enum InstanceType:
  * Introduce FIRST/LAST_SPEC_OBJECT_TYPE that ranges over all types that
    represent JS objects, and use that consistently to check language types.
  * Rename FIRST/LAST_JS_OBJECT_TYPE and FIRST/LAST_FUNCTION_CLASS_TYPE
    to FIRST/LAST_[NON]CALLABLE_SPEC_OBJECT_TYPE for clarity.
  * Eliminate the overlap over JS_REGEXP_TYPE.
  * Also replace FIRST_JS_OBJECT with FIRST_JS_RECEIVER, but only use it where
    we exclusively talk about the internal representation type.
  * Insert JS_PROXY and JS_FUNCTION_PROXY in the appropriate places.

- Fix all checks concerning classification, especially for functions, to
  use the CALLABLE_SPEC_OBJECT range (that includes funciton proxies).

- Handle proxies in SetProperty (that was the easiest part :) ).

- A few simple test cases.

e14402b1df A first skeleton for introducing Harmony proxies. 
1) Add new type JSProxy for representing proxy objects.
   Currently devoid of functionality, i.e., all properties are undefined.

2) Some rudimentary global $Proxy functions to create proxies.

Next step: Hook up getProperty and getOwnProperty handlers. Will probably
require introducing a new LookupResult type, which is a mixture of
INTERCEPTOR (handles any property) and CALLBACK (calls back to JS).
Can we unify this somehow?

TODO: Should probably rename existing Proxy type to something like
"Foreign", to avoid confusion.

ec58c05f4e Add support for startup data (snapshot) compression. 
This is for mobile platforms where application footprint size is
important. To avoid including compression libraries into V8, we assume
that the host machine have them (true for Linux), and rely on embedder
to provide decompressed data.

Currently, only snapshot data can be comressed. It is also possible to
compress libraries sources, but it is more involved and will be
addressed in another CL.

9cca7d2733 Combine typed and pixel arrays. 
Worth mentioning:
- Specialized versions of pixel array and store/loads inside the generic stubs have been removed, since to have parity for all external arrays, 8 different versions would have to be inlined/checked.
- There's a new constant in v8.h for external arrays with pixel array elements.
