Régis Crelier 1ddb120eaa [vm/bytecode] Improve bytecode debugger.
While stepping, do not stop more than once in the same token range.
Adjusted tests expecting multiple stops at same location.
Fixed emitted source position of DebugCheck opcode in async op.
Ignore all possible breakpoint positions until the first DebugCheck opcode of
the function, so as to not stop in the prologue where arguments are not yet
accessible.
Fixed look up of context level in debugger.
Use receiver to look up async op closure in frame instead of named captured
variable.
Made StoreContextVar a 'debug checked' opcode.
Implemented rewind of interpreted frames.
Marked get_source_report_test as (temporarily) failing in status file.
Removed fixed and passing regression test from status file.

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.

Issue https://github.com/dart-lang/sdk/issues/36648
Issue https://github.com/dart-lang/sdk/issues/36097

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.

Martin Kustermann b75057b687 [vm/concurrency] Introduce concept of Isolate Groups
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.

When a mixin class is created, there might be anonymous closures copied over to the other script.
Previously the script of closure function is the script of its parent function, which is not true in that case.
The solution is to create a patch class as the owner if parent function has a different script object. Return script of owner when query for script of closure function.

Debugger will retrieve the saved context object when looking for IsAtAsyncJump(). The saved context object does not match the context level if setting breakpoint on "break" statement.
It is because when flowgraph builds break statement, DebugStepCheck was put after context object was restored to its parent. Then activation frame got the parent context when pausing at breakpoint.
