Aske Simon Christensen 50efd7f187 [Kernel] Add list of unused arguments to InstanceCreation nodes. 
During constant evaluation, unused arguments to a const constructor are
thrown away after evaluation, since their values do not affect the
resulting instance constant. If such an unused argument ends up
unevaluated, any errors that would arise in the final evaluation are
not reported.

This CL adds space in the Kernel AST for saving these unevaluated
expressions so they can be checked during final constant evaluation.

Even though this is an incompatible change, no update is needed to the
VM code (except for the version bump), since the VM does not support
InstanceCreation nodes in the first place.

Ryan Macnak 1e24fe7d69 [vm, compiler] Specialize unoptimized monomorphic and megamorphic calls. 
dart-bytecode, arm64:            +4.742% geomean
dart-bytecode-jit-unopt, arm64: +12.73% geomean
dart2js-compile, x64:            +3.635% geomean

In the polymorphic and unlinked cases, call to a stub the does a linear scan against an ICData.

In the monomorphic case, call to a prologue of the expected target function that checks the expected receiver class. There is additional indirection in the JIT version compared to the AOT version to also tick a usage counter so the inliner can make good decisions.

In the megamorphic case, call to a stub that does a hash table lookup against a MegamorphicCache.

Megamorphic call sites face a loss of precision in usage counts. The call site count is not recorded and the usage counter of the target function is used as an approximation.

Monomorphic and megamorphic calls sites are reset to the polymorphic/unlinked state on hot reload.

Monomorphic and megamorphic calls sites do not check the stepping state, so they are reset to the polymorphic/unlinked state when stepping begins and disabled.

Back-edges now increment the usage counter in addition to checking it. This ensures function with loops containing monomorphic calls will eventually cross the optimization threshold.

Fixed backwards use of kMonomorphicEntryOffset and kPolymorphicEntryOffset.

Fixed C stack overflow when bouncing between the KBC interpreter and a simulator.

Aart Bik fa6fce61fa [dart/vm] Improved inlining methods and heuristics 
Rationale:
Previous method cached graph information (instruction and call site
counts) on a per-function level, not accounting for potential
specializations. The improved method runs an extra constant folding
pass, and only caches per-function information for non-specialized
cases. As a result, we inling much better, see for example, the
added test as illustration.

Since we no longer cache for constants, compile-time may be increased
a bit due to the extra scan. In the long run we should consider
for common constant "situations" as the call site.

Jonas Termansen 3972f738ca [security] [dart:io] Fix current directory being in front of PATH. 
This is a security improvement.

On Linux and Android, starting a process with Process.run, Process.runSync
or Process.start would first search the current directory before searching
PATH (Issue [37101][]). Operating systems other than Linux and Android
didn't have this behavior and aren't affected by this vulnerability.

Effectively this puts the current working directory in the front of PATH,
even if it wasn't in the PATH.

This change fixes that vulnerability and only searches the directories in
the PATH environment variable.

asiva 7e9a4b786d [VM/benchmarks] Rework Dart2JSCompileAll test to instead do CFE compile all 
The Dart2JSCompileAll test has not been working for a while due to
- issues with package config
- issues with getting the sources compiled with CFE after the switch to
  kernel pipeline.
Revised this benchmark/test to instead load the kernel_service dill file and do a CompileAll of CFE.

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:
```
