When deserializing the startup snapshot, call IterateStrongRoots with VISIT_FOR_SERIALIZATION rather than VISIT_ONLY_STRONG. To compensate, make the StartupDeserializer explicitly iterate over the partial snapshot cache. This makes the deserializer and serializer consistent in their use of the function and makes their differences explicit in the snapshot code itself.

- Fix ParseBCP47 to return just the extension. The second argument to substr function is actually the length, not the end position of the substring :') - Remove extension keys that aren't part of the relevant extension keys - Use 'ca' as an relevant extension key for DateTimeFormat - Use the canonicalized locale tag after create the ICU locale is created, rather than the input locale tag.

This is to ensure the snapshot is deterministic. Internal fields can contain: - reference to heap object - embedder-defined aligned pointer - a smi The latter two are not distinguishable by V8, so if the serializer callback returns non-zero value, we consider it to be an aligned pointer and clear it to ensure that the snapshot does not contain memory addresses that may not be deterministic. If the callback returns { nullptr, 0 } as result, we consider it to be a smi or some in-place data that we then serialize verbatim.

Instead of passing and storing uint8_t* and size_t, we now more often store a Vector or OwnedVector, which encapsulates these two fields. This provides some more DCHECKs which happen automatically when getting a subvector into the buffer. Drive-by: More refactorings and removals of unneeded or rarely used helper methods.

Currently to obtain a v8::Array out of a C array or a std::vector, one needs to loop through the elements and call array->Set() multiple times, and these calls go into v8::Object::Set() which can be slow. This patch adds a new Array::New overload that converts a Local<Value>* with known size into a Local<Array>.

Unlike other v8::Context getter on v8::Isolate, the v8::Context returned by GetEnteredOrMicrotaskContext may be non-NativeContext. However, Blink implicitly assumes all v8::Context is backed by NativeContexts. This CL updates GetEnteredOrMicrotaskContext() to check the resulting Context is NativeContext, and updates callers of EnterMicrotaskContext to use NativeContext.

This is resurrecting an optimization from the pre-torque version. Avoid allocating another sequential string for the result when there's only one element, just return the ToString-ed element. This not only saves time writing to this destination string, but also reduce GC pressure. The System Health Memory Benchmark (load:media:google_images) exposed this missing optimization with a 15% regression in memory usage. Very large external strings were being copied into V8's heap as sequential string.
