I've sampled (eagerly) reading the VM platform, a compilation of
dart2js, a compilation of "flutter gallery" and a compilation of a big
internal app, and reordered switch cases accordingly.
I can't measure any difference in runtime, but have a hard time
thinking it's not better.
I've included the tool that does the sampling.

This changes tool/fasta.dart to run the subcommand in the same VM when
no VM arguments are specified. This speeds up the tool and as a
consequence speeds up the tool/update_all.dart and
tool/update_expectation.dart tools.

This CL adds a tool that can compare the class hierarchies of two dill files.
Currently it only checks for public classes and their public supertypes.
We could extend the tool later if needed.
Currently it gives this for flutter:
```
$ out/ReleaseX64/dart pkg/kernel/bin/compare_hierarchies.dart /path/to/flutter/bin/cache/flutter_web_sdk/kernel/flutter_ddc_sdk_sound.dill /path/to/flutter/bin/cache/artifacts/engine/common/flutter_patched_sdk/platform_strong.dill "dart:nativewrappers#NativeFieldWrapperClass1"
(1): /path/to/flutter/bin/cache/flutter_web_sdk/kernel/flutter_ddc_sdk_sound.dill
(2): /path/to/flutter/bin/cache/artifacts/engine/common/flutter_patched_sdk/platform_strong.dill
Missing classes in lib dart:_internal
In (2) but not in (1): [VMLibraryHooks, Lists, VMInternalsForTesting, ClassID]
Missing classes in lib dart:ui
In (1) but not in (2): [PlatformViewRegistry]
Class(ColorFilter) in dart.ui from (2) has these extra supertypes: [ImageFilter (dart:ui)]
```
where the last line is https://github.com/dart-lang/sdk/issues/48245
It gives this for the dart sdk:
```
$ out/ReleaseX64/dart pkg/kernel/bin/compare_hierarchies.dart out/ReleaseX64/vm_platform_strong.dill out/ReleaseX64/ddc_platform_sound.dill "dart:nativewrappers#NativeFieldWrapperClass1"
(1): out/ReleaseX64/vm_platform_strong.dill
(2): out/ReleaseX64/ddc_platform_sound.dill
Missing classes in lib dart:_internal
In (1) but not in (2): [VMLibraryHooks, Lists, VMInternalsForTesting, ClassID]
```
which seems fine (dart:_internal after all)

Tool will try to extract useful information from invalid (e.g. partial
or wrong version) dill.
This is a first stab and could possibly be extended and improved in the
future.

When we perform constant evaluation in the CFE, the async transform
runs after constant evaluation. Thus, it can no longer use const
bool.fromEnvironment("dart.vm.product") to query whether the VM is
in product mode.
Instead, it can read the product mode define directly from the
environment defines given to the CFE and generate different code
depending on the value.

Make the constant evaluator take an explicit error reporter so we have
to opt in to using the "simple" one that reports errors in an ad hoc
way. This is the start of a change to use Fasta-controlled error
messages throughout and eventually get rid of the simple error
handler, and to continue constant evaluation after the first constant
error.

This flag was always true so we can remove it and specialize the
remaining code that used it. The only code that used it was in the
Dart VM's async transformation.
Specializing that code led to some unused fields in the async helper
class which were removed. This triggered me to look at core types
which seems to have a lot of unused stuff.

* Ensure that we have a .dill file and it has the correct version before
we start decoding it in dump.dart.
* Throw errors, not strings. Ensure that they have a useful
toString().
* Do not print usage except when the command is invoked
incorrectly (wrong number of arguments). Once we get into the
command it's less likely that it's been invoked incorrectly and more
likely that something else has gone wrong.
Because these utilities are invoked from other scripts (like the
fasta command), printing their usage for problems other than
invoking them correctly doesn't match the way that they were invoked
and it's confusing.
