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!

3b2470d296 Fix presubmit errors catched by a more recent version of cpplint.py.
Mainly, there were errors concerning blank lines before and after class access
control sections [whitespace/blank_line].

BEFORE an access control section (e.g. public:, private:) there should be a
blank line (except for the section right after the class declaration).

AFTER an access control section there should be no blank line.

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.

c5fc4b9099 Add asserts and state tracking to ensure that we do not call
into C++ without having a valid stack frame that can be
traversed at GC.
Also add asserts to track that we do not try to generate a stub
while we are generating a stub, since the stub creation code is
not GC safe.

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.

of heap snapshot, I will deal with this later. Heap objects and
references previously missing in snapshot are now marked as 'hidden'.
That means, they not shown to user, but participate in sizes

 - meta-information in JSON snapshot is no more double encoded.

d4bc8e1585 New Heap profiler: add dumping HeapNumbers and InternalFields to snapshot.
HeapNumbers do consume memory, so it's worth dumping them. However, we
don't dump their values, as they are not as self-descriptive as values
of strings, and they will increase snapshot size. Storing heap numbers
values can be added if we will feel a sufficient demand for that.

InternalFields are used, e.g. for storing references to DOM nodes
event handlers.

2388079051 Implement heap snapshots serialization into JSON. API is designed
to avoid storing serialized snapshot on VM, instead it is emitted
using output stream interface.

The size of JSON emitted is roughly equal to used heap size
(when stored as an ASCII string).

Now a whole heap snapshot can be serialized and transmitted outside
VM. This makes possible:
  - implementing non-async UI for heap snapshots inspection;
  - storing heap snapshots for further inspection;
  - remote profiling (we can even implement a snapshotting mode
    where a snapshot isn't even stored in VM, only transmitted --
    good for mobile devices);
  - creating tools for outside heap snapshots processing, e.g.
    converting to HPROF.

57769489d5 First phase of migration to new indexed property query callbacks.
Eventually indexed property query callbacks will return attributes
(as an integer) or an empty handle if property is not intercepted.

To gradually migrate to this new API, USE_NEW_QUERY_CALLBACK
macro would control if old or new style API is used.

So the migration plan is:

1) introduce new API which should be explictily enabled;
2) switch to new API defining USE_NEW_QUERY_CALLBACK before
include of <v8.h> (that would require changes to client code as well)
3) remove old API from v8
4) remove #define USE_NEW_QUERY_CALLBACK from clients.

1695003bb9 Heap profiler: reduce heap snapshots size.
The size of a snapshot is now 65-80% of the JS heap size (tested on
GMail and Wave), previously it was >200%.

793d0a92b9 Add a check that weak object handle is not in NEAR_DEATH state after weak callback invocation.
If object enters NEAR_DEATH state, it must be explicitly cleared and/or disposed, otherwise
it would retain JS object forever.  Note as well that parameter is reset to NULL on first
invocation so weak handle callback would be in hard situation.

35a80e1624 Landing for hans@chromium.org.
TYPE_CHECK in v8.h should assign to volatile qualified null-pointer.

Unless the pointer is volatile qualified, Clang will warn that LLVM
removes the assignment during optimization. This is not a problem as
that code should never execute, but the warning is treated as an error
when building Chromium, and thus stops the build.

c98ac6e82c Heap profiler: implement diffing of snapshots.
To trace objects between snapshots, an external map of object tags is
maintained. After the first heap snapshot has been taken, the map is
updated by reporting object moves from the GC. If no snapshots were
taken, there is no overhead (except for flag checking).

I considered graph comparison algorithms that doesn't require using
object tags, but they are all of a high computational complexity, and
will still fail to detect object moves properly, even for trivial
cases, so using tags looks like unavoidable.
