Jonas Termansen	6f66f82625	[benchmark] Fork benchmarks for null safety and pin internal ones. This change forks the benchmarks for the null safety feature where there now is a null safe version at benchmarks/Foo/dart and a legacy Dart 2 version at benchmarks/Foo/dart2. This change allows benchmarks to be migrated per go/dart-nnbd-benchmark-migration. Additionally this change pins the internal benchmarks which have been moved into their own repository and is now versioned along with the Dart SDK. The dart2 implementation will be benchmarked instead of the null safe dart implementation as of this change. The null safe dart implementation will be used when null safe benchmarking is turned on.

[benchmark] Fork benchmarks for null safety and pin internal ones.

This change forks the benchmarks for the null safety feature where there
now is a null safe version at benchmarks/Foo/dart and a legacy Dart 2
version at benchmarks/Foo/dart2. This change allows benchmarks to be
migrated per go/dart-nnbd-benchmark-migration.

Additionally this change pins the internal benchmarks which have been
moved into their own repository and is now versioned along with the Dart
SDK.

The dart2 implementation will be benchmarked instead of the null safe
dart implementation as of this change. The null safe dart implementation
will be used when null safe benchmarking is turned on.

[vm/isolates] Introduce sendAndExit.

sendAndExit allows for fast data passing from worker isolate back to
parent.

[vm/benchmarks] Add benchmark that decodes json on a separate isolate.

To see advantage of running decoding on separate isolate this benchmark decodes 10 json strings.
Sync implementation has to do it sequentially, async version does in parallel.
