Daco Harkes f98a2138b7 [vm] Run clang-format on code base
When uploading CLs, the presubmit checks verify that the lines in the
diff are formatted correctly according to `git cl format runtime`.

However, when `buildtools/<os>-<arch>/clang/bin/clang-format` is
updated, it does not force reformatting of files that would be
reformatted.

This leads to two issues:
* Inconsistent style within the code base and within a single file.
* Spurious reformatting in CLs when (1) clang-format is used on the
  whole file, or (2) the diff lines overlap.

`clang-format` doesn't change that frequently, so in general this is
not a large issue, but I've seen a bit too many "spurious formatting,
please revert" comments on CLs recently.

This CL formats the runtime to be in line with the current pinned
`clang-format`:

```
$ find runtime/ -iname *.h -o -iname *.cc | xargs buildtools/mac-arm64/clang/bin/clang-format -i
```

`git cl format` (which only formats changed lines, and does so with
`clang-format`) seems to not agree with itself, or clang-format, or
cpplint in a handful of places. This CL adds `// clang-format off`
for these. (See previous patchsets for the specific instances.)

TEST=A variety of bots including GCC, MacOS and Windows.

Jens Johansen 73466729f3 [vm] Pass offset and script uri for expression compilation
This CL passes the offset and uri of the file (here called a script uri
as opposed to a library uri, the two will be different if we're in a
part) when doing expression compilation.

This CL only passes the data, but doesn't actually use it.
Future CL(s) will use this data to calculate the static type of
available variables which is needed for an upcomming feature.

Martin Kustermann 8d802dd78a [vm] Avoid embedding sources in CFE compilations if we AppJit
Creation of AppJit snapshot will not include the source of [Script]
objects (see `UntaggedScript::snapshot_to`). As a result there's no
point in letting the CFE embed the sources into the kernel if we
only use it to create an AppJit snapshot.

This is also in line with build rules for our dart-sdk, where we do the
kernel compilation separately, see utils/application_snapshot.gni:

```
  template("application_snapshot") {
    ...
    # Build the kernel file using the prebuilt VM to speed up the
    # debug and simulator builds.
    prebuilt_dart_action(target_name + "_dill") {
      ...

      args = [
        ...
        "--no-embed-sources",
        ...
      ]
      [[[
    }
    ...
  }

Martin Kustermann 2e2d542969 [vm/concurrency] Use isolate group id as key for incremental compiler for reload
As part of implementing hot-reload for isolate groups, we have to ensure
reloads on a group are performed using the same state of incremental
compiler.

This means we cannot use a specific isolate's information (such as it's
main port) for reloading purposes. Instead we use the unqiue isolate
group id when communicating with the kernel service.

Previous version

only worked if the dill was loaded via
Dart_LoadScriptFromKernel where script_kernel_size was set,
and when the platform dill could be loaded from a file called the right
thing.

This CL makes it work for Dart_LoadLibraryFromKernel too and allows
the VM to send the platform along (explicitly or implicitly) and only
tries to load the platform from a file with the right name if no
platform is given in any of the inputs.

This should fix http://b/148776866

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/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.
