Previously, KernelIsolate::CompileExpressionToKernel was called
with is_static == false and klass == nullptr, which doesn't make sense:
this call requested to compile expression inside instance method context but
without enclosing class. This results in a malformed kernel AST and crash
in bytecode generator.
Fixes vm/cc/LinkedHashMap and vm/cc/Service_* tests in bytecode mode.

Enter a safepoint when waiting for child isolate spawns to complete, since the child isolate now requires its parent (along with all other members of the isolate group) to participate in safepoints.

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.

A number of places in the code will free `Dart_KernelCompilationResult.kernel`
if non-nullptr even if `Dart_KernelCompilationResult.error` is non-nullptr.
Normally the two are mutually exclusive (either `error` is set or `kernel` is set) but
some code frees both if they are non-null.
This issue has caused free() of uninitialized memory which in return
caused some of our benchmarks to break.

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.)
