It looks like this code was implemented in the wrong place. At some
point reading the code (possibly during Kernel backend port), I noticed
this and left a TODO. This CL implements the solution described in it.

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.

This constitutes a breaking change, so the analyzer major version
number is bumped to 36. Clients that have stopped using the removed
data structures (and the methods associated with them) should be
unaffected.

This moves the code into a shared location (instead of being copied to
both of the Analyzer/Kernel-based backends), and removes support for
detecting type parameters in constants, which was allowed by strong
mode but is not legal in Dart 2.

See https://github.com/tc39/proposal-regexp-named-groups
for a high-level description of the feature and examples. This is one of the
features requested in https://github.com/dart-lang/sdk/issues/34935.
This is a partial implementation because while there is a way to retrieve
groups via Dart by name, it requires casting the returned Match to the
new RegExpMatch interface to avoid changing the RegExp interface.
Changing the RegExp interface will happen in a future update, since there
are other planned changes to the RegExp interface coming soon and that way
we only change it once. See https://github.com/dart-lang/sdk/issues/36171
for more details on the planned changes.
Also, since only BMP regular expressions are supported, not full
Unicode ones (i.e., those with the /u flag in ECMAscript), \k<NAME>
will only be parsed as a named back reference if there are named
captures in the string. Otherwise, the \k will be parsed as the identity
escape for backwards compatibility. The new tests illustrate this
difference.

The constant evaluator now generates all errors as Fasta diagnostic
messages. The ErrorReporter is simplified to just accept a diagnostic
message, or a notification that the constant evaluator encountered an
invalid expression (presumably put there due to an earlier error).
Also, the flow of control between the error reporter and the internal
abort exceptions is reversed, so the error reporter is now called as a
result of an abort exception being caught by the evaluate method.

This is a temporary workaround to copy this file into DDC, based on
jacobr@'s suggestion. I tried to keep changes minimal.
Eventually this transform should be injected when Flutter SDK builds
DDC, rather than including it here. The transform is guarded behind
a flag, so build runner can decide whether to pass it (for now, it
could be hardcoded).

- ForStatement and ForEachStatement will be replaced by ForStatement2.
- MapLiteral and SetLiteral will be replaced by SetOrMapLiteral.
To ease the transition, the old classes are subtypes of the new
classes, so even though the analyzer still creates instances of the
old classes, clients should be able to start referring to the new
classes in their code. The analyzer will stop creating instances of
MapLiteral and SetLiteral when the experimental flags for the "UI as
code" feature are turned on, and will stop creating instances of all 4
classes when we bump the major version number (which should happen
sometime in March).
For visitors, we've updated the base classes with the following default methods:
visitForStatement(node) => visitForStatement2(node);
visitForEachStatement(node) => visitForStatement2(node);
visitMapLiteral(node) => visitSetOrMapLiteral(node);
visitSetLiteral(node) => visitSetOrMapLiteral(node);
So clients should be able to start revising their visitors to override
the new visit methods rather than the old ones, and the visit methods
in the base classes will automatically forward to the new visit
methods.
