Terry is landing the test for this. We were throwing on this:
const u4 = const String.fromEnvironment("XXXXX");
void main() {
print(u4.toString());
}

This should improve performance of these members in most cases:
- toString
- operator ==
- hashCode
- runtimeType
- noSuchMethod
The helpers for checking `null` and then dispatching to the method are now very small again. Also, because we can lookup symbolized names always, we can start taking advantage of this in our Map/Set implementations (for a follow up CL).
This also improves correctness of these helpers given JavaScript objects; we were previously falling back to calling a Dart method name like `.hashCode`, which is incorrect (except for `toString` where fallback is probably the correct behavior).

This has a few related fixes:
fix#30461, DDC now generates covariant checks for superclasses with the correct substitution.
fix#29483, Analyzer can resolve the function type literal syntax correctly when used in type bounds and type arguments.
fix#30095, replace use of DDC's StrongModeError private type with TypeError.
It also has some refactoring to simplify how DDC emits the initialization code at the start of function/method bodies. We no longer jump through AST parent pointers.

fixes#30495 - optimize subtype cache
fixes#30464 - optimize `is List`
Additional changes:
- optimize double type checks
- optimize Object type checks
- optimize FutureOr<T> checks
- optimize interface checks for some dart:core and dart:async types (List, Map, Iterable, Future, Stream, and StreamSubscription )
- optimize checks for generic class default instantiations and exact instantiation (e.g. `C<dynamic>` on any instance `C<T>`, and `C<T> on an instance of C<T>`
- optimize checks for native types
- optimize getReifiedType
- optimize dcall/dsend/dput checks to use faster Type._check pattern
- optimize instanceOf/cast functions by moving special cases to appropriate types
- optimize Object.runtimeType
- optimize JS interop type checks
- optimize all function type checks
There's more we can do (especially for class/interface types) but this should cover a lot of cases.

Eliminate numerous type checks not needed in strong mode. Use
private nullability annotations instead of inline JS to mark known
non-null variables, and to make the compiler generate null checks
for null checked variables. Use nullability annotations and code refactoring to
remove redundant null checks and to move checks out of loops.

This is the original CL plus status file fixes.
Disables auto-generated function_type tests that are not working for the Dart 2 runtime behavior, and filed #30462 to track. Also removes the separate status that was skipping these tests in DDC when $checked was unset. $checked is not a thing for Dart 2, and DDC test status should never depend on it.
This reverts commit 1b0b1a4913.

also fixes various bugs:
* setters now use the correct memberName symbol, fixes#30223
* object members work for callable classes, fixes#30213
* some test fixes to work in strong mode
* a few other small cleanups (e.g. obsolete `dart.list` is removed)

* Use "|" as the separator between module path and name.
":" is already a path character in Windows. This is why the
dartdevc tests aren't working on Windows. Because they try to do:
-sC:/some/path/blah.dart:blah
And it splits at the first ":". Oops.
* Switch to "=" for separating module path from name.
It looks a little funny when used with "--summary=", but it works fine
and is very unlikely to be used for anything else on any platform
(since we already use it as the separator between arg name and value).
this includes various cleanups found along the way:
* various issues with JS annotations, see #30043
* getGenericClass is now optimized when used in a JS builtin with a Type literal
* typed list literals should be slightly faster to create
* memoized getters used by dart:_runtime should be faster
* registerExtension should be a tad faster, and now understands JSArray
* dart.bind "safeName" hack gone in codegenerator
* JSArray<E>.runtimeType returns List<E>
* JSArray<E>.noSuchMethod works
* cleans up code that generates `setExtensionBaseClass` (used only by JSArray)
* _throwUnsafe helper for generating a `throw` in --unsafe compile mode
* fix tearoff of JS interop types (_emitSimpleIdentifier)
* fix TODO about splitting LazyJSType and AnonymousJSType
* fix is/as/cast methods on TypeRep and related classes
* fix codegenerator to not tearoff "hashCode" and "runtimeType" (they are not methods)
* fix NoSuchMethodError.toString() (update via dart2js sdk impl)

DDC was incorrectly interpreting inline JS types, and hence marking
some things as non-nullable which were nullable. This fixes that, and
also slightly improves the analyzers treatment of inline JS types.
Also fixes some incorrect inline JS type annotations in DDC patch
files.

This involves a few pieces:
- Add support to DDC for specifying the module name associated with a
given summary. This lets test.dart invoke DDC using summaries in the
build directory outside of the directory containing the test itself.
- Add support to the build scripts for building the packages. This adds
a new GN target that builds everything needed to run test.dart with
dartdevc. In particular, it invokes build_pkgs.dart to compile the
relevant packages to JS+summary so that the tests can use them.
This requires some changes to build_pkgs.dart so it can output to a
given directory.
- In test.dart, when tests are compiled with dartdevc, pass in the
summaries for the packages so they don't get compiled in. Then, when
the test is run, configure require.js with the right paths to their
JS files so they can be loaded.
I also removed a bunch of unneeded buildDir parameters being passed
around the various CompilerConfiguration class methods now that they
have direct access to the configuration.
Fix#29923.
