Don't use StoreIC_ArrayLength on frozen arrays
...
The code previously assumed that an array with fast properties must have
a writable length property. But Object.freeze() now exposes a way to make
length read-only without moving the object into slow mode. This patch
simply adds a !is_frozen check to the IC code. Any future optimizations
to attribute-setting on JSArrays will need to make similar accomodations.

MIPS: Bugfix: The general array constructor stub did not handle the case properly when it is called with a function pointer in the type cell, instead assuming that an AllocationSite object should be present.
...
Port r15555 (262c081)
Original commit message:
The case where this can happen is if the cell is uninitialized, then the
first constructor call made is to the Array function of a different
context. In that case, we'll store the function pointer in the cell,
and then go ahead and call the array constructor stub too. The bug is
fixed by checking for the AllocationSite object map. If not found, the
constructor stub goes forward with a default ElementsKind, just as in
several other cases.
A test in allocation-site-info.js was beefed up to make sure the state
chain described above is traversed.

...
properly when it is called with a function pointer in the type cell,
instead assuming that an AllocationSite object should be present. The
case where this can happen is if the cell is uninitialized, then the
first constructor call made is to the Array function of a different
context. In that case, we'll store the function pointer in the cell,
and then go ahead and call the array constructor stub too. The bug is
fixed by checking for the AllocationSite object map. If not found, the
constructor stub goes forward with a default ElementsKind, just as in
several other cases.
A test in allocation-site-info.js was beefed up to make sure the state
chain described above is traversed.

In Blink, JSTypedArray and JSDataView objects act as "wrappers" for C++

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.

Their values are not used neither by the tick processor nor by CpuProfiler so it is just a waste of space.
TickSample used to be a transport for grabbed register values to TickSample::Trace, now they are passed in a special structure RegisterState which is allocated on the stack for the sampling period.
Some common pieces were moved from platform-dependent code into Sampler::SampleStack and TickSample::Init.

Correctly report stack trace when current function is FunctionApply builtin

When pc is inside FunctionApply builtin function the top frame may be either
2) Internal stack frame created by FunctionApply itself.
In this case we know its caller's pc and can correctly resolve calling function.
1) Frame of the calling JavaScript function that invoked .apply(). In this case we have no practical reliable way to find out the caller's pc so we mark the caller's frame as 'unresolved'.
All this logic is implemented in ProfileGenerator. SafeStackFrameIterator is extended to provide type of the current top stack frame (iteration actually starts from the caller's frame as we know top function from pc).

Correctly report callstack when current function is FunctionCall builtin
...
When current function is FunctionCall builtin we have no reliable way to determine its caller function (in many cases the top of the sampled stack contains address of the caller but sometimes it does not). Instead of dropping the sample or its two top frames we simply mark the caller frame as '(unresolved function)'. It seems like a better approach that dropping whole sample as knowing the top function and the rest of the stack the user should be able to figure out what the caller was.
This change adds builtin id to CodeEntry objects. It will be used later to add similar top frame analysis for FunctionApply and probably other builtins.

Correctly report callstack when current function is FunctionCall builtin
...
When current function is FunctionCall builtin we have no reliable way to determine its caller function (in many cases the top of the sampled stack contains address of the caller but sometimes it does not). Instead of dropping the sample or its two top frames we simply mark the caller frame as '(unresolved function)'. It seems like a better approach that dropping whole sample as knowing the top function and the rest of the stack the user should be able to figure out what the caller was.
This change adds builtin id to CodeEntry objects. It will be used later to add similar top frame analysis for FunctionApply and probably other builtins.

Test that profiler is stopped when isolate is being disposed
...
The only way to get v8::CpuProfiler instance in the V8 public API is to call v8::Iolate::GetCpuProfiler(). The method will return NULL if the isolate has not been initialized yet or has been torn down already. It is the client's reponsibility to make sure that CPU profiling has been stopped before disposing of the isolate.
This CL adds a test for this and several ASSRTS enforcing that assumptions. This allowed to be sure that heap is always setup when CPU profiling is being started. Based on that the number of places where already compiled functions are reported to the profiler event processor boils down to the single place (CpuProfiler::StartProcessorIfNotStarted). I'm going to rely on this assumption in further changes.

CpuProfiler: eliminate 2 layers of 4 for CodeCreateEvent calls.

The bodies of methods in ProfilerEventProcessor were moved into CpuProfiler.
Multiple NewCodeEntry methods in CpuProfilesCollection were replaced with one which
simply passes arguments to the CodeEntry constructor.
And CpuProfiler just calls this method when it needs a CodeEntry object.
This NewCodeEntry method is required because CpuProfilesCollection keeps ownership of CodeEntry objects.

Fix infinite loop in regress-opt-after-deopt.

%CompleteOptimization attempts to install optimized functions
that the parallel thread has put on the output queue, as long as
the function is marked with a builtin. However, activating the
debugger will set all functions to the lazy recompile builtin,
without the function being on the parallel recompilation pipeline.
So we wait for the function to finish parallel recompilation
while it's marked by a builtin that's unrelated to parallel
recompilation.

Extract StackFrameIteratorBase
...
This change introduces StackFrameIteratorBase which owns singleton frame instances and encapsulates some basic iterator functionality. It has two actual implementations: StackFrameIterator and SafeStackFrameIterator.
All logic specific to frame iteration at a random point (basically checks that fp and sp extracted from stack frames are within current stack boundaries) used only by CPU profiler is now concentrated in SafeStackFrameIterator.
Generic stack iteration used in all other places is put into StackFrameIterator. Also this iterator unlike SafeStackFrameIterator iterates through stack handlers.
StackAddressValidator and ExitFrameValidator classes were removed in favor of inline checks and simple methods.

Do not iterate stack handlers in SafeStackFrameIterator
...
CPU profiler doesn't use stack handlers so there is no need to iterate through them while traversing stack. This change SafeStackFrameIterator always iterate only frames and removes checks corresponding to the handlers iteration.
The problem described in the bug occurred because of a false assumption in SafeStackFrameIterator that if Isolate::c_entry_fp is not NULL then the top frame on the stack is always a C++ frame. It is false because we may have entered JS code again, in which case JS_ENTRY code stub generated by JSEntryStub::GenerateBody() will save current c_entry_fp value but not reset it to NULL and after that it will create ENTRY stack frame and JS_ENTRY handler on the stack and put the latter into Isolate::handler(top). This means that if we start iterating from c_entry_fp frame and try to compare the frame's sp with Isolate::handler()->address() it will turn out that frame->sp() > handler->address() and the condition in SafeStackFrameIterator::CanIterateHandles is not held.

Get rid of Isolate::safe_stack_iterator_counter
...
This change removes per-isolate counter of active SafeStackFrameIterators. The counter is used by stack frames implementations to avoid accessing pointers to heap objects when traversing stack for CPU profiler (so called "safe" mode). Each StackFrame instance is owned by single iterator and has a pointer to it so we can simply mark the iterator as "safe" or not and read the field in the stack frames instead of going into the isolate.

Simplify stack iterators implementation
...
In order to fix https://code.google.com/p/chromium/issues/detail?id=252097 I
need to change SafeStackTraceFrameIterator. Stack iterators hierarchy looks
excessively complicated and I'd like to flatten it a bit by removing some
intermediate classes. In particular there are two hierarchies sharing
JavaScriptFrameIteratorTemp<T> template for no good reason.
This change extracts some of JavaScriptFrameIteratorTemp functionality directly
into SafeStackTraceFrameIterator. This made it obvious that a few checks were
performed twice.
The rest of JavaScriptFrameIteratorTemp<T> is merged with
JavaScriptFrameIterator. Now that the class is not a template some of its
implementation is moved from frames-inl.h into frames.cc
So in this change I removed JavaScriptFrameIterator and
SafeJavaScriptFrameIterator. As the next step I'm going to merge
SafeStackFrameIterator into SafeStackTraceFrameIterator.

V8 API: Add a missing NULL check into Isolate::GetCurrentContext().
...
There is a missing NULL check for: "internal_isolate->context() != NULL".
Right now before calling this method one should call v8::Context::InContext()
first to perform this check, otherwise we may crash. But this static method
will do this check on the current isolate, which may not be the same as a given one.

MIPS: Generators: Avoid calling into runtime if operand stack is empty
...
Port r15240 (909f716e)
Original commit message:
This patch makes yield sites save the resume continuation and context
inline. If the operand stack is empty, we can avoid a call into the
runtime. This also makes the SuspendJSGeneratorObject runtime function
less magical: it just has to save the operand stack and stack handlers.
This speeds up the following case by a factor of 3 or so:
function* until(n) {
for (var i = 0; i < n; i++)
yield i;
}
function sum(iter) {
var sum = 0;
for (var x of iter) sum += x;
return sum;
}
for (var i = 0; i < 10000; i++) sum(until(1000))
Also, there is no more sentinel value as the generators will resume in
the right place already, allowing me to remove the hack added to the
--debug-code check in r14437.

Deprecate old code aging mechanism.
...
The old code aging mechanism is too agressive with flushing as it leads
to many functions being flushed and recompiled over and over again. By
now the new code aging mechanism has stabilized enough to deprecate the
old fallback mechanism.

Bugfix in hydrogen array literal code generation.
...
If an array literal contains some non-constant elements, is of type SMI, and
then the boilerplate transitions to double or fast sometime after we've
crankshafted the code, then we could incorrectly store smis in double arrays.

Do not use weak handles for ArrayBuffers.
...
Instead of allocating weak handles to free ArrayBuffer backing store, dispose of memory while walking the weak list of ArrayBuffers on GC.
Also, free all array buffers on isolate tear-down.
