Implement AggregatableHistogramTimer and use it to measure how much time
...
of running a script is really spent in compilation. That is, sum up the
total time spent compiling (parsing + compile proper) within a run call
as seen through the API.
@jochen: So many questions:
- Is it ok to re-use V8.CompileLazy?
This measures something a little different.
- clang-format does funny things to the huge macro definitions.
I accepted clang-format changes for all code, but reverted for
the #define orgies in counters.h. ok?
- Am I measuring the right thing. That is, are Aggregat[ing|ed]TimerScope
in the right place?
I'll fiddle a bit more with this to see if it does the right thing. Would
be happy if you could still review now-ish.

ClearInterrupt was invoked as it might have already started execution.

The idea behind of this solution is to use the existing "relocation info" instead of consumption the CodeLinePosition events emitted by the V8 compilers.
...
During generation code and relocation info are generated simultaneously.
When code generation is done you each code object has associated "relocation info".
Relocation information lets V8 to mark interesting places in the generated code: the pointers that might need to be relocated (after garbage collection),
correspondences between the machine program counter and source locations for stack walking.
This patch:
1. Add more source positions info in reloc info to make it suitable for source level mapping.
The amount of data should not be increased dramatically because (1) V8 already marks interesting places in the generated code and
(2) V8 does not write redundant information (it writes a pair (pc_offset, pos) only if pos is changed and skips other).
I measured it on Octane benchmark - for unoptimized code the number of source positions may achieve 2x ('lin_solve' from NavierStokes benchmark).
2. When a sample happens, CPU profiler finds a code object by pc, then use its reloc info to match the sample to a source line.
If a source line is found that hit counter is increased by one for this line.
3. Add a new public V8 API to get the hit source lines by CDT CPU profiler.
Note that it's expected a minor patch in Blink to pack the source level info in JSON to be shown.
4.Add a test that checks how the samples are distributed through source lines.
It tests two cases: (1) relocation info created during code generation and (2) relocation info associated with precompiled function's version.

Update ObjectToString to Harmony-draft algorithm
...
Updates Object.prototype.toString() to use algorithm described in harmony drafts.
Currently, the behaviour is essentially the same as ES262's version, however this changes when internal structures
such as Promise make use of symbolToStringTag (as they are supposed to, see v8:3241), and changes further once
Symbol.toStringTag is exposed publicly.

Extend CPU profiler with mapping ticks to source lines
...
The idea behind of this solution is to use the existing "relocation info" instead of consumption the CodeLinePosition events emitted by the V8 compilers.
During generation code and relocation info are generated simultaneously.
When code generation is done you each code object has associated "relocation info".
Relocation information lets V8 to mark interesting places in the generated code: the pointers that might need to be relocated (after garbage collection),
correspondences between the machine program counter and source locations for stack walking.
This patch:
1. Add more source positions info in reloc info to make it suitable for source level mapping.
The amount of data should not be increased dramatically because (1) V8 already marks interesting places in the generated code and
(2) V8 does not write redundant information (it writes a pair (pc_offset, pos) only if pos is changed and skips other).
I measured it on Octane benchmark - for unoptimized code the number of source positions may achieve 2x ('lin_solve' from NavierStokes benchmark).
2. When a sample happens, CPU profiler finds a code object by pc, then use its reloc info to match the sample to a source line.
If a source line is found that hit counter is increased by one for this line.
3. Add a new public V8 API to get the hit source lines by CDT CPU profiler.
Note that it's expected a minor patch in Blink to pack the source level info in JSON to be shown.
4.Add a test that checks how the samples are distributed through source lines.
It tests two cases: (1) relocation info created during code generation and (2) relocation info associated with precompiled function's version.

Move configuration of ResourceConstraints to Isolate construction

We can only set resource constraints before the isolate is initialized.
Since in the future, we want to initialize isolates at construction
time, we need to set constraints there.
It's possible to later modify the stack limit, so introduce an
Isolate::SetStackLimit method for that.
The SetResourceConstraints method will be deprecated. Users should pass
ResourceConstraints to Isolate::New, and use Isolate::SetStackLimit to
later modify the stack limit.

Currently, a new isolate is created in an uninitialized state, and
...
several API methods will automatically initialize it. During this
uninitialized state, code event handlers and function entry handlers can
be attached to the isolate.
This CL deprecates SetFunctionEntryHook and moves the configuration of
those handlers to the Isolate factory method.
This will allow for initializing the Isolate at creation time in the
future.
Users of V8::SetFunctionEntryHook should pass the entry hook to
Isolate::New instead. V8::SetJitCodeEventHandler should either be passed
to Isolate::New as well, or (if startup events are not required) invoked
via the Isolate.

Replace our homegrown ARRAY_SIZE() with Chrome's arraysize().
...
Our own ARRAY_SIZE() was pretty bad at error checking. If you use
arrasize() in a wrong way, the compiler will issue an error instead of
silently doing the wrong thing. The previous ARRAY_SIZE() macro is still
available as ARRAYSIZE_UNSAFE() similar to Chrome.

Change ScriptCompiler::CompileOptions to allow for two 'cache' modes
...
(parser or code) and to be explicit about cache consumption or production
(rather than making presence of cached_data imply one or the other.)
Also add a --cache flag to d8, to allow testing the functionality.
-----------------------------
API change
Reason: Currently, V8 supports a 'parser cache' for repeatedly executing the same script. We'd like to add a 2nd mode that would cache code, and would like to let the embedder decide which mode they chose (if any).
Note: Previously, the 'use cached data' property was implied by the presence of the cached data itself. (That is, kNoCompileOptions and source->cached_data != NULL.) That is no longer sufficient, since the presence of data is no longer sufficient to determine /which kind/ of data is present.
Changes from old behaviour:
- If you previously didn't use caching, nothing changes.
Example:
v8::CompileUnbound(isolate, source, kNoCompileOptions);
- If you previously used caching, it worked like this:
- 1st run:
v8::CompileUnbound(isolate, source, kProduceToCache);
Then, source->cached_data would contain the
data-to-be cached. This remains the same, except you
need to tell V8 which type of data you want.
v8::CompileUnbound(isolate, source, kProduceParserCache);
- 2nd run:
v8::CompileUnbound(isolate, source, kNoCompileOptions);
with source->cached_data set to the data you received in
the first run. This will now ignore the cached data, and
you need to explicitly tell V8 to use it:
v8::CompileUnbound(isolate, source, kConsumeParserCache);

Esp. add a per-isolate API to set the stats counter callbacks and
make it possible to set the stats counter callback after the isolate
was touched.
Embedders should use e.g. isolate->SetCounterFunction(callback) instead
of v8::V8::SetCounterFunction(callback).

Move microtask queueing logic from JavaScript to C++
...
This avoids the appearence of a leak due to storing a JSObject
as the microtask_state in the strong root list, and allows callers
to call Isolate::RunMicrotasks() without having any v8::Context
available (as at least Blink has interest in doing).
The queue is now a strong root, represented as a FixedArray of JSFunctions
(or empty_fixed_array, if it's empty); it doubles in size when it needs to grow.
The number of elements in the queue is stored in Isolate::pending_microtask_count().

Re-enable Object.observe and add enforcement for security invariants.
...
This patch reverts r21062 which disabled Object.observe and the relevant tests.
It also adds enforcement for the following three invariants:
1) No observer may receive a change record describing changes to an object which is in different security origin (context have differing security tokens)
2) No observer may receive a change record whose context's security token is different from that of the object described by the change.
3) Object.getNotifier will return null if the caller and the provided object are in differing security origins
Further, it ensures that the global object can never be observed nor a notifier retrieved for it.
Tests are included.
