Node.js is using AdjustAmountOfExternalAllocatedMemory to get
external memory from V8 [1]. In addition, they have a unittest
that verifies that AdjustAmountOfExternalAllocatedMemory returns
the correct value [2]. This CL proposes a new way to report
external memory through HeapStatistics.

Removes all V8_DEPRECATED functions that weren't recently marked as well
any V8_DEPRECATE_SOON function that relied on using the address of

Normally we would have advanced the V8_DEPRECATE_SOON methods to

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.

kPromiseRejectAfterResolved
kPromiseResolveAfterResolved
which are used to detect (and signal) misuse of the Promise constructor.
Specifically the common bug like
new Promise((res, rej) => {

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.

This extends the ScriptCompiler::CompileModule function with a
CompileOptions argument. Accepted values are kNoCompileOptions (in
which case, behavior remains unmodified) and kConsumeCodeCache. If the
latter is passed, we try to fetch the given module from the code
cache.
Since it is possible to compile the same source code as both a script
and a module (and different code is generated for the two cases), a
new is_module bit is added to the SerializedCodeData header to
disambiguate between the two cases.

The dedicated type disambiguates the two.
This also adds an overload for CreateCodeCache which takes an unbound

Creating a new instance from a v8::Function will invoke its
constructor. If it is an API callback that has not been marked as
kHasNoSideEffect, this CL introduces a way to invoke it without
throwing.
Calls within the constructor are still checked for side effects.

This method is intended for use by code caching as follows:
1. The module is compiled (and perhaps instantiated).
2. The embedder fetches and stores the module's unbound script (i.e.
the shared function info).
3. Module evaluation, maybe triggering lazy compilation.
4. Generated code for the module (which hangs off the shared function
info) is inserted into the code cache.
Subsequent module loads can load from the code cache prior to
evaluation.

As with other code size stats, this doesn't distinguish between live and
dead objects, and doesn't scan the young generation.
Also make ExternalString::is_short() const.

When only_terminate_in_safe_scope flag is passed as CreateParams for
v8::Isolate, V8 does not trigger intrruption for termination if there
is no explicit SafeForTerminationeScope.
Scope enables termination only in direct v8 calls, any recursive calls
require explicit SafeForTerminationScope.

At the moment, the isolate is allocated and initialized in a single
step. This has the downside that the platform cannot register the
isolate before the isolate gets initialized, and therefore the platform
is not available for the isolate during initialization. With this CL we
register the uninitialized isolate on the platform and initialize the
isolate after that.
This change is needed to allow the creation of task runners already
during the initialization of the isolate.

These functions are now unused within V8, as we need tighter control in
mksnapshot for creating embedded.cc.
Embedders should switch to using SnapshotCreator directly.
