38ac7fe658 [wasm] API renames for wasm serialization/deserialization
This incorporates recent feedback:
- simpler deserialization API by dropping the std::unique_ptr.
The only purpose there was communicating to the caller that they
own the buffer, and that the deserializer won't delete it. The new
design communicates that through a naming choice.
- renamed *UncompiledBytes to *WasmWireBytes

610fe2892b [Tracing] Remove State Sampling Profiling
The state sampling was implemented in chrome, we had an interface for it
V8 but it was not implemented yet.
The chrome version version has been removed in
https://codereview.chromium.org/2406703002/
Therefore following up with its removal in V8 as well.

This CL can land independent of the Chromium related CL.

9d2051fc28 [modules] Store Module metadata in per-Context EmbedderData
This is a re-land of https://codereview.chromium.org/2393303002/ with
an additional call to DisposeModuleEmbedderData() added to fix lsan failures.

Unifies the approaches used for storing the specifier -> module mapping
and the module -> directory mapping, using std::unordered_maps for both
and storing them per-Context.

This requires adding a method to the v8::Module API to get a hash code
for a Module, but allows slimming down the API in return: gone are
SetEmbedderData/GetEmbedderData, along with the fourth argument
to ResolveModuleCallback.

Besides a simpler API, this allows d8 to get closer to the HTML loader,
which requires each Realm to have a persistent module map (though this
capability is not yet exercised by any tests).

917ef616cc [wasm] Support recompilation if deserialization fails.
One step closer to the informally-agreed upon specification
that structured cloning will always succeed, meaning, if
we fail to deserialize (e.g. because version mismatch in
serialized format and v8 version), we recompile.

As part of this work, the deserializer will need to become
more resilient to invalid input data, and fail graciously
rather than CHECK-ing. This CL addresses some of that,
sufficient to unblock the current serialization tests.
Subsequent CLs will add more testing and the appropriate
fixes.

cf127e8144 [modules] Expand API to allow linking and use it in d8
This patch gives the ability for the embedder to ask for the
module requests of a module, and to pass a ResolveCallback
into Module::Instantiate().

In d8, I've implemented a simple module_map that's used
along with this API to allow loading, compiling, instantiating,
and evaluating a whole tree of modules.

No path resolution is yet implemented, meaning that all
import paths are relative to whatever directory d8 runs
in. And no imports are linked to the exports of the
requested module.

5a97e95520 Handle errors in v8::ValueDeserializer by throwing exceptions.
This restores the contract that all API methods that return Maybe<T> or
MaybeLocal<T> always throw an exception when they return nothing.

Since v8::ValueDeserializer::ReadHeader can now throw exceptions, it
needs a Local<Context> parameter so that it can set up execution state
(entering the context, etc.). The old method has been marked for
deprecation, but since this API is experimental I intend to remove it
as soon as I've removed the use from Blink.

value-serializer-unittest has been updated to expect an exception in
all decode failure cases.

7c401bd84c [api] Add interceptor for defineProperty().
With the Indexed/GenericNamedPropertyDefinerCallback it is possible to intercept Object.defineProperty() calls.

Requests that call JSReceiver::OrdinaryDefineOwnProperty() internally, also trigger the interceptor. This includes Object.freeze(), Object.preventExtensions(), and Object.seal().

As without this patch, the query interceptor triggers on
defineProperty, unless the definer callback
intercepts the request.

b4c1aefb9c Refactor data structures for simple stack traces
Simple stack traces are captured through Isolate::CaptureSimpleStackTrace.
Captured frames are stored in a FixedArray, which in turn is stored as a
property (using a private symbol) on the error object itself. Actual formatting
of the textual stack trace is done lazily when the user reads the stack
property of the error object.

This would involve many conversions back and forth between index-encoded raw
data (receiver, function, offset and code), JS CallSite objects, and C++
CallSite objects.

This commit refactors the C++ CallSite class into a Struct class called
StackTraceFrame, which is the new single point of truth frame information.
Isolate::CaptureSimpleStackTrace stores an array of StackTraceFrames, and JS
CallSite objects (now created only when the user specifies custom stack trace
formatting through Error.prepareStackTrace) internally only store a reference
to a StackTraceFrame.

821c3e563c Reland [Tracing] V8 Tracing Controller
V8 has had a trace event macro interface for while, but without a tracing
controller a standalone V8 would be unable to collect traces.

This CL introduces a complete Tracing Controller system for V8.
It is fully function except that it does not yet store trace event args.

This CL has a few components,
The tracing controller itself, contributed by the author of this CL
The Trace config (including the parser), contributed by lpy@
The Trace Object, Trace Writer, and Trace Buffer are all contributed by rksang@

BUG=v8:4561
LOG=N

The original CL was failing the V8 Arm Builder:
https://build.chromium.org/p/client.v8.ports/builders/V8%20Arm%20-%20builder/builds/2456
and the V8 Mips Builder:
https://build.chromium.org/p/client.v8.ports/builders/V8%20Mips%20-%20builder/builds/2506

The failure is due to undefined behavior of CHECK_EQ of 2 const char*

3d59845267 [Tracing] V8 Tracing Controller
V8 has had a trace event macro interface for while, but without a tracing
controller a standalone V8 would be unable to collect traces.

This CL introduces a complete Tracing Controller system for V8.
It is fully function except that it does not yet store trace event args.

This CL has a few components,
The tracing controller itself, contributed by the author of this CL
The Trace config (including the parser), contributed by lpy@
The Trace Object, Trace Writer, and Trace Buffer are all contributed by rksang@

0abba43524 [stubs] Improve code generation for ToBoolean.
Introduce a proper CodeStubAssembler::BranchIfToBooleanIsTrue helper
method, that branches to if_true/if_false labels depending on whether
the value that is passed would yield true or false when fed to
ToBoolean. Use this helper to implement the bytecode handlers w/o having
to materialize the temporary booleans and essentially branching twice.
The CodeStubAssembler::BranchIfToBooleanIsTrue helper favors the most
likely case of a Boolean constant now.

Also migrate the ToBooleanStub to a ToBoolean TurboFan builtin, that
also uses the helper method under the hood.

Remove the now obsolete Oddball::to_boolean field.
