Dart for-in loops allow `var x = [1]; for (var x in x) {}`, which is not
allowed in JS. If this pattern is detected, a temporary variable is
introduced so the for-in initializer expression is evaluated outside of
the JS for-of loop.
(This issue seems to be unique to for-in loops. For loops and other
kinds of variable declarations of the form `var x = ...` are not
allowed to use `x` in the initializer, even if `x` is declared in an
outer scope.)
Also fixes an out-of-date comment in the DDC+Analyzer backend.

Adds an option for specifying the output JS module name if that is
needed (only applies for some module formats).
Also removes repl-compile (it's set via API, not the command line).
Refactors dartdevk options to match dartdevc so we can migrate more
easily. Moves shared code into a shared location and removes copied
code.

This uses optional new/const and `=` in named argument defaults.
All changes are automated, except for:
- utils/dartdevc/BUILD.gn: run DDC build scripts with --preview-dart-2
- pkg/dev_compiler/tool/patch_sdk.dart: add a TODO that Analyzer doesn't
supporting implicit const in libraries.dart
- pkg/dev_compiler/tool/input_sdk/libraries.dart: was not formatted due
to the aforementioned Analyzer bug
- tools/bots/test_matrix.json: run DDC sourcemap suite in Dart 2 mode
- pkg/pkg.status: skip pkg/dev_compiler if running in Dart 1 mode

This works around broken FunctionTypeImpl.== in Analyzer. Also
makes DDK's type naming heuristic more consistent with DDC.

There are a few bug fixes here as well. Most notably, `.name.name`
instead of `.name` in DDK's analysis of virtual accessors. DDC/K's
handling of spread arguments in JS interop was also fairly broken
(it was generating a RestParameter instead of Spread). There's
also a lot of cleanup in js_ast as well, to make it a bit more
type safe.

This ports a fairly large part of DDC's Analyzer-based code generator,
however most nodes are not supported yet.
The goal is to preserve all functionality of code that was ported,
except for deprecated features (e.g. mirrors, fuzzy arrows, libraryRoot).

This makes the source files a little easier to read anyway and the JSON
is not typically that nested so there should be a minimal statup performance hit.
Do not return the JSON as an escaped String to work around a strange v8 bug.

Make DDC a better platform for debugging by ensuring that stack traces
generated by DDC even when using the raw dart:core StackTrace class
apply JS source maps and benefit from the polish provided by the
stack_trace package.
stack_trace_mapper.dart needs to be compiled to js and included on your
page to benefit from this functionality. Otherwise you will still see
regular JS stack traces as usual.
