Jens Johansen fa88e0c91f [analyzer] Add benchmarks of running dart analyze
This CL:
  * Adds a benchmark of running `dart analyze` on a single small file.
  * Adds a benchmark of running `dart analyze` on a single project.
  * Adds a benchmark of running `dart analyze` on several projects.
  * Adds a hidden flag to `dart analyze` so it reports ram usage:
    run via `dart analyze --format=json --memory` and the memory
    usage will be reported in the json output.

All the bencmarks run without and with cache for speed testing, and
without and with cache when measuring memory usage.

The idea of running this via `dart analyze` instead of running either
the script or the snapshot is to measure the "real world" speed which
could be different (although in practise it _does_ just run the
snapshot).

Future CL(s) should also add benchmarks for queries using the
language server.

Analysis Server Benchmarks

How to run the benchmarks

To see a list of all available benchmarks, run:

dart benchmark/benchmarks.dart list

To run an individual benchmark, run:

dart benchmark/benchmarks.dart run <benchmark-id>

How they're tested

In order to make sure that our benchmarks don't regress in terms of their ability to run, we create one unit test per benchmark, and run those tests as part of our normal CI test suite.

To save time on the CI, we only run one iteration of each benchmark (--repeat=1), and we run the benchmark on a smaller data set (--quick).

See test/benchmark_test.dart.

To add a new benchmark

Register the new benchmark in the main() method of benchmark/benchmarks.dart.

On the bots

Our benchmarks run on a continuous performance testing system. Currently, the benchmarks need to be manually registered ahead of time.
