Martin Kustermann 20962e656b [vm/concurrency] Split up IsolateReloadContext into IsolateReloadContext/IsolateGroupReloadContext
Similar to the split of ClassTable into ClassTable/SharedClassTable,
this CL splits up the IsolateReloadContext into:

  * IsolateGroupReloadContext: Consists of reload-related information across all
    isolates. The [Reload()] method is split up in phases that are
    performed on all isolates before the next phase is started.

    => This allows each isolate to add reasons for rolling back, if no
       reasons are found the reload will be accepted atomically.

  * IsolateReloadContext: Constists of reload-related information for a
    particular isolate (e.g. mappings of old to new classes)

The assumption is that all isolates have the same source (and therefore
the same libraries). For certain things, e.g. discovering which libraries
changed, it is necessary to examine the object store. We use the first
isolate in a group (but could use any of them) to do so, since the
isolate group does not have this information atm.

This is a preparation CL for supporting hot-reloading multiple isolates
within one isolate group. Though the support in this CL stays at having
only a single isolate in a group.

  => This CL turns off FLAG_enable_isolate_groups in JIT mode.

Martin Kustermann 4c5028d139 [vm/concurrency] Make an IsolateGroup object which will contain group-specific resources
The isolate group object will keep a doubly-linked list of all isolates
within it's group. This will allow us to later on iterate all isolates
within a group for e.g. GC purposes.

The isolate group object will eventually hold the shared heap, thread registry
and other resources. This CL is only the start.

Alexander Aprelev 0425997b31 Second attempt to reland "[vm/concurrency] Introduce concept of Isolate Groups"
This reverts commit 3d14b75f97.

An Isolate Group (IG) is a collection of isolates which were spawned from the
same source. This allows the VM to:

  * have a guarantee that all isolates within one IG can safely exchange
    structured objects (currently we rely on embedder for this
    guarantee)

  * hot-reload all isolates together (currently we only reload one
    isolate, leaving same-source isolates in inconsistent state)

  * make a shared heap for all isolates from the same IG, which paves
    the way for faster communication and sharing of immutable objects.

All isolates within one IG will share the same IsolateGroupSource.

**Embedder changes**

This change makes breaking embedder API changes to support this new
concept of Isolate Groups: The existing isolate lifecycle callbacks
given to Dart_Initialize will become Isolate Group lifecycle callbacks.
A new callback `initialize_isolate` callback will be added which can
initialize a new isolate within an existing IG.

Existing embedders can be updated by performing the following renames

  Dart_CreateIsolate -> Dart_CreateIsolateGroup
  Dart_IsolateCreateCallback -> Dart_IsolateGroupCreateCallback
  Dart_IsolateCleanupCallback -> Dart_IsolateGroupShutdownCallback
  Dart_CreateIsolateFromKernel -> Dart_CreateIsolateGroupFromKernel
  Dart_CurrentIsolateData -> Dart_CurrentIsolateGroupData
  Dart_IsolateData -> Dart_IsolateGroupData
  Dart_GetNativeIsolateData -> Dart_GetNativeIsolateGroupData
  Dart_InitializeParams.create -> Dart_InitializeParams.create_group
  Dart_InitializeParams.cleanup -> Dart_InitializeParams.shutdown_group
  Dart_InitializeParams.shutdown -> Dart_InitializeParams.shutdown_isolate

By default `Isolate.spawn` will cause the creation of a new IG.

Though an embedder can opt-into supporting multiple isolates within one IG by
providing a callback to the newly added `Dart_InitializeParams.initialize_isolate`.
The responsibility of this new callback is to initialize an existing
isolate (which was setup by re-using source code from the spawning
isolate - i.e. the one which used `Isolate.spawn`) by setting native
resolvers, initializing global state, etc.

Original review: https://dart-review.googlesource.com/c/sdk/+/105241

Difference to original review:

  * Give each isolate it's own [Loader] (for now)
  * Sort classes during initialization for spawned isolates if app-jit is used (to match main isolate)
  * Fix IsolateData memory leak if isolate startup fails

Difference to first reland(Patchset 2):

  * Fix typo where memory was freed twice.

Alexander Aprelev 4ccae238ea [vm/isolate] Add TransferableTypedData class that allows low-cost passing of Uint8List between isolates.
TransferableTypedData instances are one-use kind of thing: once receiver materializes it, it can't be used
again, once sender sends it out to an isolate, sender can't send it to different isolate.

Example of use:

sender isolate:

```
Future<TransferableTypedData> consolidateHttpClientResponseBytes(HttpClientResponse response) {
  final completer = Completer<TransferableTypedData>();
  final chunks = <Uint8List>[];
  response.listen((List<int> chunk) {
    chunks.add(chunk);
  }, onDone: () {
    completer.complete(TransferableTypedData.fromList(chunks));
  });
  return completer.future;
}
...
sendPort.send(await consolidateHttpClientResponseBytes(response));
```

receiver isolate:
```
    RawReceivePort port = RawReceivePort((TransferableTypedData transferable) {
      Uint8List content = transferable.materialize().asUint8List();
      ...
    });
```

31959[tr] and 31960[tr] tests were inspired by dartbug.com/31959, dartbug.com/31960 that this CL attempts to address:

Matthew Dempsky a53c12d07a [vm] Use std::unique_ptr with Message
Message is a C++ type with a simple ownership model appropriate for
std::unique_ptr. This CL applies the following changes:

1. All uses of "new Message(...)" are replaced with
"Message::New(...)", which is effectively
"std::make_unique<Message>(...)". (The latter was only added in C++14,
but Dart still compiles in C++11 mode.)

2. All owning Message* are replaced with std::unique_ptr<Message>. The
notable exception is MessageQueue, which still uses raw Message*
internally to simplify the linked list handling.

3. All "delete message;" statements are removed.

4. Uses of "NULL" replaced with "nullptr" as necessary.

Alexander Aprelev 7d14785115 This relands "Load isolate from parent's kernel in Isolate.spawn calls.".
Original PR was reverted because it broke hot-reload bots. This CL adds steps to initialize kernel_service compiler for child isolate. Compiler is needed to support hot-reload request. Child isolate's compiler is created from full kernel file produced by main isolate's compiler. Changes since original PR are pkg/vm/bin/kernel_service.dart in pkg/vm/lib/incremental_compiler.dart.

Further this CL changes kernel fingerprint calculation for interface types so it calculates the hash of the canonical names themselves, rather than indices(that might change from one compilation to another).

This reverts commit 63fd8f63e6.

Ryan Macnak 7514ce941e [vm] Assert handles are only allocated when the thread is preventing safepoints.
Threads in the native or blocked states don't prevent safepoints, so they may run concurrently with a safepoint operation like GC. It is not safe for handles to be allocated while the GC is visiting them, so these threads must not allocate handles. Assert only threads in the VM or generated states, which prevent safepoints until they check in, may allocate handles. (Generated code does not allocate handles, but leaf runtime entries remain in the generated state.)

Martin Kustermann 3b057dea98 [VM] Remove legacy Object::empty_context() and CTX constant
Our generated code does not keep the context in a special register
anymore (for quite some time now).  The context is just another definition
in the IR language and gets assigned register locations by the linearscan
register allocator.

Furthermore we no longer use an empty context for closures which have no
captured states, instead the context of those closures is just `null`.

This CL therefore removes Object::empty_context() and the CTX constant.

Alexander Markov bc937b3b6b Reapply CL "Option to truncate integers to 64 bits, part 2"
This is the 2nd attempt to land the CL
abed3c2a70

Original review: https://codereview.chromium.org/2982823002
No extra changes were made. Large literals in the Dart core library
which caused failures during the previous attempt to land this CL have
been fixed separately.

Description of the CL:

In --limit-ints-to-64-bits mode:
* Integer constructors return Integer::null if integer is out of range.
* Error is reported for integer literals which are out of range.
* Dart API is revised to return errors if integers are out of range.

Bigint::IsDisabled() method is introduced to be able to enable/disable
Bigints independently of --limit-ints-to-64-bits mode in future.

Deprecated constructor Integer::NewFromUint64 is replaced with
Integer::New in certain cases.
