Stress test for comparing analysis performed in two AnalysisContext instances with different option…

Stress test for comparing analysis performed in two AnalysisContext instances with different options.

It takes a Git repository, a folder in this repository and creates two
AnalysisContext instances - with experimental and with stable
analysis options. Then for each Git revision it applies the changes
to Dart files in the folder to both contexts, analyzes and compares
analysis cache results.

The current implementation sets "finerGrainedInvalidation" to true for the experimental context.

The code duplication between this and the stress test in server makes me sad,
but I suppose it's better to get this checked in and then fix the problem later,
so lgtm.

File pkg/analyzer/test/stress/for_git_repository.dart (right):

https://codereview.chromium.org/2206783002/diff/1/pkg/analyzer/test/stress/fo...
pkg/analyzer/test/stress/for_git_repository.dart:227: String folderPath =
'/Users/scheglov/tmp/limited-invalidation/sdk/pkg/analyzer';
Needs to not have machine specific paths. Can we make these command-line
arguments?
