The data structure isn't optimized (recording data into it takes
O(n^2) time, where n is the number of unreachable nodes in the file),
and we don't need it for normal execution anyhow.
Following the model used by CFE and dart2js, the analysis driver has a
new flag `retainDataForTesting` to control whether the test data is
gathered, so that under normal execution there is no overhead. The
testing data is stored in a new class `TestingData`; we can expand
this class in the future if we need to record other intermediate
analysis results for testing.

Add a "-s" (succinct) option to have a more dense output.
Meant for use together with "-a" so one can get a quick overview of how
many tests fail, e.g.
out/ReleaseX64/dart pkg/front_end/test/id_testing/id_testing_test.dart -a -s

We still verify that the analyzer passes these tests, but we now do
the verification using the "ID test" mechanism that's shared with the
CFE. This will allow the front end to run these tests as soon as its
integration with flow analysis is complete.
Still to do: migrate tests of type promotion and definite assignment
so that they can be shared by the front end.

This CL reworks the tests flow_analysis_test.dart and
type_promotion_test.dart to make use of the framework recently
introduced into pkg/front_end/lib/src/testing/id.dart. The long term
goal is to move these tests into a common location so that they can
exercise both the front end and the analyzer.

The AST refactor for "UI as code" left behind a few things whose names
ended in "2". This CL deprecates those things and creates
replacements that don't end in "2", so that we keep the API clean. In
a future breaking change release of the analyzer we'll remove the
deprecated things.
The following methods and classes are added:
- ForStatement and ForStatementImpl
- ListLiteral.elements
- SetOrMapLiteral.elements
- AstVisitor.visitForStatement
- AstFactory.forStatement
- NodeLintRegistry.addForStatement
The following methods and classes are deprecated:
- ForStatement2 and ForStatement2Impl
- ListLiteral.elements2
- SetOrMapLiteral.elements2
- AstVisitor.visitForStatement2
- AstFactory.forStatement2
- NodeLintRegistry.addForStatement2
In a similar way to how we did the previous stage of AST migration,
the existing visitors have been modified so that the default
implementation of visitForStatement2 redirects to visitForStatement;
this allows clients to change their overrides of visitForStatement2 to
override visitForStatement instead. Once all clients have been
migrated we will be able to delete the visitForStatement2 method.

ba5644b76c fixed an analyzer bug causing
a crash when a top level variable requiring type inference contained a
closure involving type promotion, and removed some explicit types that
were present in the analyzer to work around the bug.
Although the bug has been fixed now, the fix hasn't rolled out in a
release of the SDK. So to avoid people seeing analysis server crashes
when editing the analyzer, I'm re-introducing the workaround.

Promotion analysis requires the localVariableInfo data structures to
be set; these are set by the VariableResolverVisitor. So we need to
ensure that this visitor runs prior to type inference.
