[vm] Const map, remove invalid assert
Isolates are allowed to race each other to initialize _indexNullable, the last isolate wins. See https://dart-review.googlesource.com/c/sdk/+/210726 and https://dart-review.googlesource.com/c/sdk/+/203765. These asserts were wrong, because another isolate could have initialized _indexNullable in between places calling _createIndex and _createIndex itself. Closes: https://github.com/dart-lang/sdk/issues/47118 Change-Id: I5d55b9715ef622737a6f70c0b57590076ece3225 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/212586 Reviewed-by: Martin Kustermann <kustermann@google.com> Commit-Queue: Daco Harkes <dacoharkes@google.com>
