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: ``` ╰─➤ out/ReleaseX64/dart 31960.dart sending... 163ms for round-trip sending... 81ms for round-trip sending... 20ms for round-trip sending... 14ms for round-trip sending... 20ms for round-trip sending... 14ms for round-trip ``` (notice no "since last checking" pauses") vs ``` ╰─➤ out/ReleaseX64/dart 31960.dart sending... 154ms since last checkin 174ms for round-trip sending... 68ms since last checkin 9ms since last checkin 171ms for round-trip sending... 13ms since last checkin 108ms for round-trip sending... 14ms since last checkin 108ms for round-trip sending... 14ms since last checkin 107ms for round-trip ``` Change-Id: I0fcb5ce285394f498c3f1db4414204531f98199d Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/99623 Commit-Queue: Alexander Aprelev <aam@google.com> Reviewed-by: Ryan Macnak <rmacnak@google.com> Reviewed-by: Lasse R.H.
