Martin Kustermann c8ebfcd739 [vm] Remove unused code related to RedirectionData
Since the transition from Source based to Kernel based frontend to the
Dart VM, we have not supported callable redirecting factories. This has
caused all removed code in this CL to be unused and untested!

The support for reifing redirection related information would mainly be
used by embedder / dart:mirrors. Right now its not used by anyone and
the kernel support was never implemented.

I suggest we remove the unused and untested code until a decision has
been made that we actually want to support it - in which case it can be
properly implemented, possibly by re-using some of the deleted code in
this CL.

TEST=CL removes unused code, no test result changes.

Martin Kustermann 1ca55a1fba [vm/concurrency] Call _startIsolate (which has entrypoint annotation) instead of _delayEntrypointInvocation (which does not)
The former calls the latter with the same arguments, so we could call
the latter directly, though we prefer to use `_startIsolate()` as the
entrypoint.

This fixes test failures in obfuscated mode, where the runtime cannot
find the `_delayEntrypointInvocation` function.

Martin Kustermann d9561e5a1d [vm/concurrency] Move Isolate.spawn()-related logic out of runtime/vm/ into runtime/lib
The Isolate.spawn() is part of our dart:isolate library implementation,
it should therefore preferrably live under runtime/lib folder.

This CL does that as well as removing some special message handling
logic by using the new `Dart_RunLoopAsync()` C API, which results in
net removal of code.

As a nice side-effect it also makes isolate spawning slightly faster due
to avoiding extra safepoint/vm<->native transitions.

Issue https://github.com/dart-lang/sdk/issues/44088

TEST=Changes existing implementation, have existing test coverage for it.

Martin Kustermann bf4280ff75 [vm/concurrency] Add Dart_CreateLightweightIsolate/Dart_RunLoopAsync APIs
Dart_CreateLightweightIsolate API:

  This API can be used by embedders to create a lightweight isolate
  (inside an existing isolate group).

  It is the analogous to Dart_CreateIsolateGroup - though taking a
  parent isolate as parameter (inside whose IG we create a new isolate)
  instead of taking kernel/snapshot data.

  Right now this API works on AOT and returns an error in JIT, both cases
  are covered by the test.

Dart_RunLoopAsync:

  The API can be used by embedders to transfer ownership of an isolate to
  the VM, which will take care of running the message handling loop and
  shuts the isolate down once the last receive port has been closed.

  It does allow listening to error/exit events generated by the message
  loop implementation as well as allows setting errors-are-fatal,
  effectively the same event-loop related parameters from the
  `Isolate.spawn()` API, just in Dart.

  It's the embedders responsibility to first launch initial dart code
  which will take care of responding to events (i.e. directly/indirectly
  open a receive port) - otherwise the isolate cannot be talked to and
  would immediately shut down.

Since our vm/cc tests do support running in AOT, we use a hybrid
approach to test the functionality: We let a normal Dart test call a
small C wrapper using FFI, to create a lightweight isolate, run it on a
new thread and join that thread.

Martin Kustermann 42ac762949 [vm/concurrency] Fix inconsistency in Dart's spawn implementation
When Dart invokes Isolate.spawn the Dart VM calls out to the embedder to
create an isolate (group) or initialize it (in case of lightweight
isolates).

  * If the embedder doesn't implement this functionality or fails to
    perform the creation/initialization, it will signal this failure
    via the return value it gives to the VM in the call back
    implementation (i.e. Dart_InitializeParams.create_group and
    Dart_InitializeParams.initialize_isolate}).

  * If the embeder sucessfully completed it's work, the VM owns the
    isolate after the embedder call returns. The VM is then responsible
    for running it.

It is an undocumented invariant atm that the embedder is responsible
to make the isolate runnable if it signals the VM that isolate was
sucessfully created/initialized.
  => If it does not do that, we have effectively an isolate leak.
  => Though right now seemingly all of our embedders to that correctly.

To avoid this unintentional isolate leak we make the isolate runnable
ourselves if embedder callback was successful but did not make it
runnable itself.

  => This also avoids unnecessary ceremony code in the embedders that
     look like this:

      Dart_ExitIsolate();
      Dart_IsolateMakeRunnable(child);
      Dart_EnterIsolate(child);

The implementation of `Dart_IsolateMakeRunnable()` had an untested and
unused code path that caused running the isolate (on a thread pool).
This is not documented and can lead to bugs because often the
embedders enter the isolate right after making it runnable (e.g. above
code sequence) - which would be racing with the spawned message handler
thread.

  => Furtunately our embedders are well behaved and make the isolate
     runnable during the callback.
  => As a safeguard we'll make `Dart_IsolateMakeRunnable()` return an
     error if it's called outside the callback (which we can detect by
     the presense of a spawn state)

Ben Konyi b729693cb9 [ VM ] Allow for Timer to set its ReceivePort as active / inactive to
prevent repeated port allocations

Flutter makes heavy use of short-lived Timers which currently causes
repeated opening/closing of the Timer port. This change allows for
RawReceivePorts to be set active / inactive, allowing for a port to be
kept open but not considered alive.

After dart-lang/sdk@d5118d5: "notifyListener2_iteration": 1639.0

Tess Strickland fe2f9aca21 [vm] Move dynamic checks into DartEntry::InvokeCallable.
DartEntry::InvokeCallable (and DartEntry::InvokeClosure) are only called
for dynamic invocations. Instead of making it the responsibility of the
caller to check the callable function if it can't receive dynamic
invocation, move the call to DoArgumentTypesMatch into
DartEntry::InvokeCallable.

Since all current callers of these and related functions already have a
handle on the current thread, thread it through instead of retrieving it
via Thread::Current().

Tess Strickland 72cfc5c638 [vm] Clean up handling of payload-containing objects.
This CL adds a new PAYLOAD_SIZEOF specification to
runtime_offsets_list.h which defines InstanceSize methods given an
method name to invoke to get the header size (i.e., the size of
the object portion before the payload).

It uses this new specification to create appropriate InstanceSize()
methods for objects written to read-only sections of snapshots,
instead of needing separate size calculations for SIMARM_X64.

It adds more methods to Instructions to avoid special casing for bare
instructions mode. It also removes the special casing for SIMARM_X64,
serializing all read-only objects in the same manner even when not
in a crossword situation.

In kernel files assertion conditions are specified as a range of source
positions. Sometimes source texts are not available and VM cannot
extract assertion condition text, so Script::GetSnippet returns null.

With null safety it is no longer valid to pass null as a non-nullable
argument '_failedAssertion' of _AssertionError._create constructor,
so we should provide a valid String. This change converts 'null'
assertion condition text to "<optimized out>", similarly to AOT mode.

Ryan Macnak d8c5f19e01 [vm] Remove hard-coded prohibition of using Isolate.spawnUri with AOT.
This was originally added to prevent fork bombs in our test suite. Early versions of AOT for the standalone VM loaded the AOT program based on LD_LIBRARY_PATH instead of the command line arguments, so tests the tried to spawn a second script spawned themselves. The VM snapshot has since also been changed to be the same for every app, and some embedders already load multiple apps into the same process using the C API.

Embedders can still block any Isolate.spawn or spawnUri in the C callbacks if they don't want to implement loading for secondary isolates.

Tess Strickland bb24f76c72 [vm] Reland "Remove non-covariant checks from closure bodies (part 1)"
Also relands the followup CLs:
"Perform non-covariant checks when dynamically invoking callables."
"Use AreValidArguments so that names are checked as well."

Original description of first CL:

This change only affects compilation when running in non-precompiled
mode with --no-lazy-dispatchers enabled.

Instead of always compiling in non-covariant checks, even for closures
not called dynamically, remove the non-covariant checks from the closure
and instead do the non-covariant checks for dynamic calls during the
NoSuchMethodForCallStub fallback by calling
Function::DoArgumentTypesMatch.

Adds two overloads for Function::DoArgumentTypesMatch, one which takes a
function type argument vector and one which takes neither an
instantiator type argument vector or a function type argument vector.
For the versions that are not explicitly passed a type argument vector,
an appropriate one is constructed using the arguments. If there is not
enough information in the arguments, then we fall back to assuming the
empty type argument vector for the instantiator case and instantiating
to bounds in the function type argument case.

Fixes Function::DoArgumentTypesMatch to handle generic functions and to
check arguments appropriately according to the active null safety mode.
For generic functions, the provided or resulting function type vector
has non-covariant checks performed against the type parameter bounds.

This change uncovered one test that was incorrectly passing in strong
mode, see https://github.com/dart-lang/sdk/issues/42688 for details.

Original description of second CL:

The VM only does this when the callable function does not expect dynamic
invocations. Otherwise, performing the checks would be redundant, as the
function body already contains the appropriate non-covariant checks.

Third CL had no additional description.

Ryan Macnak c5a94db091 [vm] Initial implementation of deferred loading.
(Assignment of libraries to loading units is already done in the kernel generation step.)

After compiling and before serializing, we walk the program and for each Code we assign its Instructions, CodeSourceMap and CompressedStackMap to the loading unit of that Code's defining library. Deduplication may cause Instructions, CodeSourceMaps and CompressedStackMaps to belong to more than one loading unit; in this case the objects are assigned to the root loading unit. Later they can be more precisely assigned to the dominating loading unit.

All objects except some Instructions, CodeSourceMaps and CompressedStackMaps belong to the root loading unit's snapshot. This snapshot is written like an unsplit snapshot, except that when serializing Code, we will write a reference to a stub or null when the Code's Instructions, CodeSourceMap or CompressedStackMap belongs to a non-root loading unit. The snapshots of non-root loading units contain these deferred objects and references to the corresponding Code objects to patch. The types of objects we defer (Instructions, CodeSourceMaps and CompressedStackMaps) usually represent 70+% of the snapshot size.

Bare instructions mode must be disabled when splitting because we cannot have PC-relative calls between loading units. Later we can re-enable this for calls within loading units.

Broken: Compactor probably crashes we can now have an unbounded number of image pages and the compactor assumes a fixed number.

Embedder's guide:

At compile-time, gen_snapshot should be passed --loading_unit_manifest with a path, which will enable splitting and output a mapping from loading unit ids to snapshot output paths.

At runtime, sometime during isolate startup, an embedder should call Dart_SetDeferredLoadHandler, probably near an existing call to Dart_SetLibraryTagHandler. The callback is given a loading unit id, and should eventually call Dart_DeferredLoadComplete[Error].

This CL also includes Native API versioning to deal with possible
version skew between native api version against which native libraries
are compiled and the version in the DartVM the code is run on.

The subset of symbols in the CL includes handle related symbols, error
