Now that I'm able to open the entire SDK in VSC, I'm fixing some of the analysis issues in various files (carefully) without changing their meaning. In this case, I removed unnecessary imports from benchmarks. In regexp_benchmark I ignored one warning which likely would have changed the behavior of the code. BUG=https://github.com/dart-lang/sdk/issues/52419 Change-Id: I9a195a4e45121313bd9f065f2579a165c3fec05b Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/303901 Auto-Submit: Eric Seidel <eric@shorebird.dev> Reviewed-by: William Hesse <whesse@google.com> Commit-Queue: William Hesse <whesse@google.com>
