This removes the @fields and @=fields canonical name
encodings that allowed for encoding of conflicting members
and didn't support field<->getter/setter conversion
between dills or between outline and full dill.

save the coverage into the dill file.

This changes the reported failure from Crash to something more specific
to the encounter error, like ExpectationFileMismatch. Validation errors
for the .yaml file still produce Crash, and so does a couple of the
checks on Component integrity that were also used outside
incremental_load_from_dill_suite.dart

This increases our "local" coverage of the constant evaluator.
Run with something like
`pkg/front_end/test/fasta/strong_tester.dart -DupdateExpectations=true -DstressConstantEvaluator=true -DskipVm=true`
there is now almost coverage of everything (or a comment in the code
suggests that the path is probably unreachable).
Note that
`out/ReleaseX64/dart pkg/front_end/test/vm_service_coverage_constant_evaluator.dart pkg/front_end/test/fasta/strong_tester.dart -DupdateExpectations=true -DstressConstantEvaluator=true -DskipVm=true`
has erroneous misses, for instance (but not limited to) asserts.
These are caused by errors in the VM.
A follow-up CL will be created to turn on "stressConstantEvaluator" by
default and print out any sucesses in the expect files.

Previously the first file in the `Component.uriToSource` was used which
didn't work nicely with multifile tests.
Text outline expectations were already using the test description uri.

The CL reduces the number of false positive cases in the round-trip
serialization unit testing by refining the verifier analysis. Not it
doesn't attempt to make the round trip over the sub-trees containing
free variables.

This CL also includes the following changes:
- The .registerTags() method is added to the Case combinator.
- The actual canonical names' root is passed into the deserializer.
- Some text serialization failures are fixed and the corresponding
status entries in text_serialization.status removed.

This CL gives the option to load classes lazily (on by default),
meaning that fields, procedures, constructors and redirecting
factory constructors of classes are not initially read,
but instead read when (or if) needed.
The idea being that many classes aren’t needed, and that
spending time on reading them is thus just a waste of time.
This is especially true in modular compilation where a lot
of modules needs to be given as input as the compilation at
hand might technically rely on it, but in practice only very
few of the classes are actually needed (or very few classes
actually need their members).
The below numbers are comparing a VM without this change and without
the lazy class hierarchy member lists change with
b31566b297 (the base change for those
two changes).
For running a simple hello-world script, on my machine 500 times
and doing statistics on it I can measure the following differences:
With verbose, from kernel_service startup to compile complete:
Difference at 95.0% confidence
-17.8 +/- 0.555817
-24.3455% +/- 0.760206%
(Student's t, pooled s = 4.48379)
With verbose, total runtime measure by `time`
Difference at 95.0% confidence
-19.346 +/- 0.905217
-12.0333% +/- 0.563051%
(Student's t, pooled s = 7.30242)
Without verbose, total runtime measure by `time`
Difference at 95.0% confidence
-17.862 +/- 0.842905
-12.0635% +/- 0.569276%
(Student's t, pooled s = 6.79974)
For running a number of modular compilations I’ve recorded an
improvement in actual runtime in the order of 20-37% depending
on the circumstance. In a real build system, though, the
difference seems to be more in the order of around 5%.
