Initiated by: goderbauer

Reason for reverting: The microbenchmark failed two run two times in a row after this was committed (see https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket/8755379171959141089/+/u/run_microbenchmarks/stdout).

microbenchmarks

To run these benchmarks on a device, first run `flutter logs' in one window to see the device logs, then, in a different window, run any of these:

flutter run --release lib/gestures/velocity_tracker_bench.dart
flutter run --release lib/gestures/gesture_detector_bench.dart
flutter run --release lib/stocks/animation_bench.dart
flutter run --release lib/stocks/build_bench.dart
flutter run --release lib/stocks/layout_bench.dart

The results should be in the device logs.

Avoid changing names of the benchmarks

Each microbenchmark is identified by a name, for example, "catmullrom_transform_iteration". Changing the name of an existing microbenchmarks will effectively remove the old benchmark and create a new one, losing the historical data associated with the old benchmark in the process.
