... when the code range is created. This key should be more helpful
than the existing kCodeSpaceFirstPageAddress crash key, especially
for the cases when snapshot does not contain Code objects and thus
the code space is not created during Isolate initialization.
The mid-term plan is to remove the latter in favour of the former
since the default configuration does not imply creation of the code
space.

Asynchronous WebAssembly compilation returns the compilation result
through resolving a result promise. So far the result promise was
resolved through V8-internal APIs. This caused problems, because
resolving promises requires correct handling of microtasks, and
microtasks are controlled by the embedder, and not by V8.
This CL adds an API to allow the embedder to resolve the result
promise itself, and handle microtasks as necessary.
The use of the new API is available in a full CL, without API dance:

This adds a new struct "OOMDetails" which is passed to the
OOMErrorCallback. It currently holds the "is_heap_oom" bool that was
also passed before, plus an optional "detail" string.
The struct can later be extended without having to change the signature
of the OOMErrorCallback. Removing fields will have to follow the
standard deprecation rules, but this is also easily possible without the
hassle for this initial change.
We modify the deprecated OOMErrorCallback definition and un-deprecate it,
which can be seen as removing a deprecated API and adding a new one in
one CL.

Due to the consistent overhead of snapshot checksum verification
we ideally want to avoid it all-together. However there are still enough
devices out there that suffer from corrupted snapshots that might
cause hard to debug heap corruptions.
This CL exposes the calculated (dummy value for now) and the expected
snapshot checksum as a crash key, so it can be easily consulted during
investigation.
Note: The calculated crash key contains 0x0 for now as a dummy value. We
will come up with a strategy later-on to limit the overhead of
calculating the checksum.

The new callback does no longer use ScriptOrModule but rather gets the
host-defined options and the referrer name as separate arguments.
This brings us one step closer to deprecate ScriptOrModule and putting
the host-defined options in the script context.
- Add v8::Data::IsFixedArray and cast helpers
- Deprecate HostImportModuleDynamicallyWithImportAssertionsCallback soon
- Add Script::Run entry point that explicitly takes host-defined

the origin trial the feature flag value has to be loaded from blink.
This CL stores the value of the --wasm-dynamic-tiering flag in the

flag. The flag value gets loaded from blink when a new NativeModule is
created.

This moves every single class/function out of include/v8.h into a
separate header in include/, which v8.h then includes so that
externally nothing appears to have changed.
Every include of v8.h from inside v8 has been changed to a more
fine-grained include.
Previously inline functions defined at the bottom of v8.h would call
private non-inline functions in the V8 class. Since that class is now
in v8-initialization.h and is rarely included (as that would create
dependency cycles), this is not possible and so those methods have been
moved out of the V8 class into the namespace v8::api_internal.
None of the previous files in include/ now #include v8.h, which means
if embedders were relying on this transitive dependency then it will
give compile failures.
v8-inspector.h does depend on v8-scripts.h for the time being to ensure
that Chrome continue to compile but that change will be reverted once
those transitive #includes in chrome are changed to include it directly.
