TracedGlobal integrates with the use case of EmbedderHeapTracer and replaces
regular weak Global or Persistent nodes for such cases. This allows to simplify
the case for regular weak handles in a sense that they follow regular weak
semantics (if the underlying object is otherwise unreachable the weak handle
will be reset).
TracedGlobal requires slightly different semantics in the sense that it can be
required to keep them alive on Scavenge garbage collections because there's a
transitive path that is only known when using the EmbedderHeapTracer.
TracedGlobal accomodates that use case.
TracedGlobal follows move semantics and can thus be used in regular std
containers without wrapping data structure.
The internal state uses 20% less memory and allows for only iterating those
nodes when necessary. The design trades the virtual call when iterating
interesting persistents in the GC prologue with calling out through the
EmbedderHeapTracer for each node which is also a virtual call. There is one less
iteration over the set of handles required though and the design is robust
against recursive GCs that mutate the embedder state during the prologue
callback.

Note that some error messages still use the term 'neuter' since error

This API allows the embedder to provide a stack and PC, FP and
SP registers. V8 will then attempt to unwind the stack to the C++ frame
that called into JS. This API is signal-safe, meaning it does not call
any signal-unsafe OS functions or read/write any V8 state.

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.

This CL refactors the existing trap handler code for Linux to allow a
cleaner extension to Windows.
1) The CL extracts platform-specific code into separate files, see
https://docs.google.com/document/d/1HCgKIpdjy_CEodTLvZ5VuykDI6gGTHrTtau2j0zwm28.
Specifically this means:
* Move posix-specific API functions from v8.h to v8-wasm-trap-handler-posix.h.
Deprecate the existing TryHandleSignal API function.
* Move posix-specific function declarations from trap-handler-internal.h to
handler-inside-posix.h
* Move posix-specific function definitions from handler-shared.cc to
handler-outside-posix.cc
2) The CL changes filenames from *-linux.* to *-posix.*. I expect that
most of the implementation for MacOS will be the same as for Linux.

This CL replaces the stack trace parameter with a the array that is
usually passed to the JS prepareStackTrace callback. This allows two
important goals to be realized: 1) we can easily stringify individual
frames and 2) we can (if needed) call back into JS from this callback
with a usable structure. If, as is sometimes the case, a v8::StackTrace
is needed, |v8::Exception::GetStackTrace| can be used on the exception
that is passed to PrepareStackTraceCallback.

Move everything defined in the v8::internal namespace from include/v8.h
into a separate header that can be included by globals.h/checks.h
instead of the whole v8.h.
Also moves V8_EXPORT into v8config.h (so it can be use in the new
v8-internal.h).

Previously explicit calls to external memory adjustment could yield in lowering
the limit below the initial default limit. The consequence is repeated useless
garbage collections when e.g. passing around ArrayBuffers.

We have an API (GetCodeRange) which gives the location of V8 code on the
heap, but builtin code no longer lives on the heap.
The upcoming work on the V8 stack unwinder requires the embedder to
provide the code ranges for both the heap and builtins, so this API will
be used there.

Currently, we use an AllocationKind to signal to the embedder how v8
has allocated the backingstore of an array buffer. The embedder then has
to implement matching logic to free an exernalized buffer. By Using
custom deleters v8 can communicate how to free an externalized array
buffer without requiring all embedders to implement corresponding
freeing logic.

This call can be used by embedder to request a GC for testing reasons.
The GC also takes the current embedder stack state as an argument that
is forwarded to the embedder when entering the atomic pause.
This way embedders can request garbage collections for testing and set
how the embedder should treat the stack.

With the callback we can check if the origin trial is turned on for a
given context.
I will not land the other CL which added a flag to the isolate. The
information if the origin trial is on is context-specific and not
isolate-specific, and it's hard on the embedder side to track all
creations of a context.
With the API proposed in this CL we will ask the embedder every time we
start compilation whether the origin trial is on or off.

Move brackets enclosing declarator in a couple of V8_DEPRECATE_SOON
cases so that the attribute is correctly placed.
I.e. should come after the class keyword and after a function signature
but before the body.
Also adds suppressions for a case where a replacement method calls
the deprecated method it replaces.

This marks the following methods as V8_DEPRECATE_SOON and adds new
versions that take Isolate* as their first parameter:
PrimitiveArray::Set
PrimitiveArray::Get
StackTrace::GetFrame
String::Write
String::WriteOneByte
String::WriteUtf8
String::Concat
StringObject::New
Additionally StackFrameInfo, Module and TemplateInfo are marked as
NeverReadOnlySpaceObject so their GetIsolates calls are safe.
In api.cc, ContextFromHeapObject is split into
ContextFromNeverReadOnlySpaceObject and UnsafeContextFromHeapObject,
where the latter uses the deprecated methods but is only called from
methods that were themselves already marked V8_DEPRECATE_SOON.
Deprecation warnings for using HeapObject::GetHeap/GetIsolate are
suppressed for all the uses in V8_DEPRECATE_SOON methods so that stats
produced using tools/collect_deprecation_stats.sh don't show them.

This is the first CL to refactor WebAssembly.instantiateStreaming to
make it spec compliant again. The design doc where the whole change is
discussed is available in the tracking bug. The tracking bug also
references prototype implementations of the whole change, which includes
the changes in this CL.
Tests for the new API functions will be added with the second V8 CL
which adds the implementation of the API functions.

Deprecates EmbedderHeapTracer::NumberOfWrappersToTrace and replaces it
with EmbedderHeapTracer::IsTracingDone.
V8 only really cares about the final state (emptiness) here and
embedders may choose implementations that have a hard time determinining
exact size for their work queues.

This extends the current Promise Rejection Hook with two new events
kPromiseRejectAfterResolved
kPromiseResolveAfterResolved
which are used to detect (and signal) misuse of the Promise constructor.
Specifically the common bug like
new Promise((res, rej) => {
res(1);
throw new Error("something")
});
where the error is silently swallowed by the Promise constructor without
the user ever noticing can be caught via this hook.

The embedder should ultimately be responsible for handling this since they
anyway give us a copy of the data. They can easily make sure that the chunks we

Changes SharedFunctionInfo to store a function_token_offset, relative
to the start_position, instead of the full function_token_position.
This enables us to reduce both FunctionTokenPosition and
ExpectedNofProperties to 16 bits each, saving 32 bits per SFI.

The name {CallerOwnedBuffer} does not make sense in all situations,
especially if such an object is returned instead of being passed as
argument.
I am working on moving the wasm wire bytes off the JS heap, and hence
will return unowned references via the API. To prepare this change, I
deprecate the existing {CallerOwnedBuffer} and introduce a new
{BufferReference} struct with proper field names.

As specified in https://tc39.github.io/ecma262/#sec-atomics-wait, the
critical section must occur before the load and comparison.
This slightly changes the `AtomicsWaitCallback` API, but in a
direction that arguably makes it more consistent.
As a drive-by fix, reset `node->waiting_` in case there
was an exception from the first callback.

Add an inspection callback for embedders that allows tracking
of `Atomics.wait()` calls in order to enable diagnostic tooling
around it, as well as providing a way to break out of an
`Atomics.wait()` call without having to fully terminate execution.
The motivation here is that this allows embedders to perform
somewhat customizable deadlock detection.
