Always mark the entire valid prefix of the descriptor array.
...
Previously we would only mark the slot that was added specifically for
this map, if there was a backpointer and the descriptor array was shared
via the backpointer. However, ConvertTransitionToMapTransition may break
this link after we marked the transitioned map, before we marked the
transitioning map. So the descriptor slots of the parent map won't get
recorded, and we potentially point to an old address of an already
relocated function.

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::CancelTerminateExecution() -- 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.

MIPS: Implement many KeyedStoreStubs using Crankshaft
...
Port r14001 (28443693)
Original commit message:
- Addition of a compiled hydrogen stub for KeyedStores.
- Inlining of "grow" stubs into OPTIMIZED_FUNCTIONs
- Addition of new "ignore OOB" ic stub that silently swallows out-of-bounds stores to external typed arrays.
- Addition of new "copy-on-write" ic stub that inlines allocation and copying operations for cow array
- New stub are generated with Crankshaft, so they are automatically inlined into OPTIMIZED_FUNCTIONs

Turn Flags into a uint32_t typedef.
...
We cannot rely on C++ compilers inferring the int-type from the enum
value range. Whereas Linux/OSX find uint32_t as type for [0,MaxUInt32],
Windows insists it's int.
Update the test to execute its original intent on all platforms: 1 value
larger than max arguments, 1 smaller than max arguments (on all
platforms). This makes the test run a lot faster.

ARM: Tweak ECMAToInt32VFP to address regression on Nexus 4

After r13912, we saw a small regression in Kraken crypto-aes and
crypto-ccm on Nexus 4. This patch, proposed by Rodolph Perfetta,
addresses that without regressing other platforms.
Instead of looking at the exponent of double_input and trying to figure
out if the conversion will overflow, eagerly do the VCVT and return
early unless it saturated.

MIPS: fix NaN handling of Isolate::StackOverflow()
...
The mjsunit/stack-traces-overflow.js test fails on MIPS target as Error.stackTraceLimit = NaN; should disable stack trace messages and Isolate::StackOverflow() assumes static_cast<int>(double NaN) < 0.
MIPS has a different NaN representation than other architectures so the NaN value casted to int is positive. This patch adds an isnan() check to make the handling of NaN uniform on all architectures.

MIPS: ES6 symbols: Allow symbols as property names
...
Port r13811 (0e64f280)
Original commit message:
Since symbols and strings share a common representation, most of this change is about consistently replacing 'String' with 'Name' in all places where property names are expected. In particular, no new logic at all is necessary for maps, property dictionaries, or transitions. :) The only places where an actual case distinction is needed have to do with generated type checks, and with conversions of names to strings (especially in logger and profiler).
Left in some TODOs wrt to the API: interceptors and native getters don't accept symbols as property names yet, because that would require extending the external v8.h.

MIPS: ES6 symbols: Implement Symbol intrinsic and basic functionality
...
Port r13786 (b5e7a82a)
Original commit message:
- 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).

ES6 symbols: Allow symbols as property names
...
Since symbols and strings share a common representation, most of this change is about consistently replacing 'String' with 'Name' in all places where property names are expected. In particular, no new logic at all is necessary for maps, property dictionaries, or transitions. :) The only places where an actual case distinction is needed have to do with generated type checks, and with conversions of names to strings (especially in logger and profiler).
Left in some TODOs wrt to the API: interceptors and native getters don't accept symbols as property names yet, because that would require extending the external v8.h.

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

Port r13781 (59f39a06)
Original commit message:
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).

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).

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.

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).

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.

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.

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.

ARM: Make DoStoreKeyedFixedDoubleArray faster; don't allow conditional Vmov
...
This patch makes us generate faster code for DoStoreKeyedFixedDoubleArray,
by using a branch rather than a conditional Vmov instruction.
Conditional VFP instructions are not a great idea in general, and it was
especially bad in this case because Vmov expands to a bunch of instructions.
For this reason, the patch also removes the 'cond' parameter from Vmov.
Thanks to Rodolph for pointing me to this!

ARM: Change signature for vmov.32 function in the assembler
...
The assembler has 8 different vmov variants. The one for vmov.32 and for moving
an immediate into a double reg only differs in the type of the second
paremeter: vmov.32 takes an int, the other takes a double.
The situation is dangerous because C++ will happily implicitly convert between
int and double.
This patch changes the signature of the vmov.32 assembler function so that it
cannot be confused with the other vmovs.

Allow full inlining of f.apply(this, arguments) calls.

This allows Crankshaft to completely inline a f.apply() dispatch if the
exact number of arguments is known and the function is constant. The
deoptimizer doesn't generate the f.apply() frame during deoptimization,
so the materialized frames look like f.apply() did a tailcall.
