090d09d685 ES6 symbols: Implement Symbol intrinsic and basic functionality
- Add --harmony-symbols flag.
- Add Symbol constructor; allow symbols as (unreplaced) return value from constructors.
- Introduce %CreateSymbol and %_IsSymbol natives and respective instructions.
- Extend 'typeof' code generation to handle symbols.
- Extend CompareIC with a UNIQUE_NAMES state that (uniformly) handles internalized strings and symbols.
- Property lookup delegates to SymbolDelegate object for symbols, which only carries the toString method.
- Extend Object.prototype.toString to recognise symbols.

Per the current draft spec, symbols are actually pseudo objects that are frozen with a null prototype and only one property (toString). For simplicity, we do not treat them as proper objects for now, although typeof will return "object". Only property access works as if they were (frozen) objects (via the internal delegate object).

05f1be1bb3 Unify deoptimizer for accessor and arguments frames.
This unifies the translation of artificial accessor stub and arguments
adaptor frames. The frame layout is the same on all architectures and
the computation code can be shared.

764e1a0fcf ES6 symbols: Introduce Symbol class, along with abstract Name class
The new instance type 'Symbol' represents ES6 symbols (a.k.a. private/unique names). Currently, symbols are simple data objects that only carry a hash code, random-generated upon allocation.

The new type 'Name' now serves as the common super class for strings and symbols, and is supposed to represent property names. We will eventually migrate APIs from String to Name for the standard key type.

Strings and symbols share the same hash field representation, via the Name class. This way, we should be able to use the same code paths for symbols and internalized strings in most cases. Also, Symbol's instance type code is allocated adjacent to internalized string codes in the enum, allowing a simple range check for the common case.

55f93b5532 Renamed "symbols" to "internalized strings" throughout the code base,
in preparation of the introduction of ES6 'symbols' (aka private/unique names).

The SymbolTable became the StringTable. I also made sure to adapt all comments. The only remaining use of the term "symbol" (other than unrelated uses in the parser and such) is now 'NewSymbol' in the API and the 'V8.KeyedLoadGenericSymbol' counter, changing which might break embedders.

The one functional change in this CL is that I removed the former 'empty_string' constant, since it is redundant given the 'empty_symbol' constant that we also had (and both were used inconsistently).

3ab255f55d Currently this mostly just moves code around.
- Later the different parts will become individual code objects that tailcall into one another.
- The mapcheck/symbol check still needs to be separated from the overall prototype-chain check so that the ICs can reuse the handlers.

dc9b817667 Send SIGPROF signals on the profiler event processor thread
The patch is based on the previous one that was rolled out: https://code.google.com/p/v8/source/detail?r=12985

On Linux sampling for CPU profiler is initiated on the profiler event processor thread, other platforms to follow.

CPU profiler continues to use SamplingCircularQueue, we will replave it with a single sample buffer when Mac and Win ports support profiling on the event processing thread.

When --prof option is specified profiling is initiated either on the profiler event processor thread if CPU profiler is on or on the  SignalSender thread as it used to if no CPU profiles are being collected.

ProfilerEventsProcessor::ProcessEventsAndDoSample now waits in a tight loop, processing collected samples until sampling interval expires. To save CPU resources I'm planning to change that to use nanosleep as only one sample is expected in the queue at any point.

95c5e68714 Fix bogus regexp test.
The reason this test fails on ARM hardware but not on Intel hardware
(including the ARM simulator) is this:
'\xa0' is interpreted as a negative signed byte number. Casting it to
uc16 sign-extends it. The resulting string does not fit into a one-byte
string, thus a two-byte string is allocated.
For some reason the code compiled for ARM does not sign-extend, and 0xa0
fits into a one-byte string. Thus a one-byte string is allocated. Trying
to cast it to two-byte causes assertion failure.

ce1e10f5fc Make __proto__ a foreign callback on Object.prototype.
This moves the __proto__ property to Object.prototype and turns it into
a callback property actually present in the descriptor array as opposed
to a hack in the properties lookup. For now it still is a "magic" data
property using foreign callbacks and not an accessor property visible to
JavaScript.

The second effect of this change is that JSON.parse() no longer treats
the __proto__ property specially, it will be defined as any other data
property. Note that object literals still have their special handling.

8f407c7b99 Move extensibility check to the top of Object.isFrozen/Object.isSealed
This speeds up isFrozen/isSealed checks on "normal" objects without
slowing down checks on frozen/sealed objects.

Though this ordering is not what ES5 specifies, the difference is not
observable (especially since the code bails out if the passed-in object
is a proxy).

30a4a798e5 Speed up non-interceptor case of Object.getOwnPropertyNames
When there are interceptors on an object, it's possible to
end up with duplicate property names. But when all the names
are provided by v8, a collision is not possible, so we can
fast-path that case by not de-duping.

Also added better test coverage for interceptor API.
