This CL is the sum of the following 5 CLs: * https://dart-review.googlesource.com/c/sdk/+/170342/ * https://dart-review.googlesource.com/c/sdk/+/170344/ * https://dart-review.googlesource.com/c/sdk/+/170345/ * https://dart-review.googlesource.com/c/sdk/+/170346/ * https://dart-review.googlesource.com/c/sdk/+/170347/ The reason for landing the 5 CLs as one CL is to prevent potential troubles with bisecting over the branch because the change is fully functional only with all 5 CLs. Closes #40122. TEST=Verified by changes in .expect files in pkg/vm/. Bug: https://github.com/dart-lang/sdk/issues/40122 Change-Id: Ib8197802fdc69694387ae47ac990c58b3aaab7a5 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/170689 Commit-Queue: Dmitry Stefantsov <dmitryas@google.com> Reviewed-by: Johnni Winther <johnniwinther@google.com>
