Johnni Winther 2d63f26ef5 Reland "[cfe] Encode field references as @getters and @setters"
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.

TEST=existing tests+add aot expectation tests

Jens Johansen 93f4ac0a83 [cfe] Actually have both ansi and plain text formatted messages (2nd try)
The CFEs FormattedMessage always had two getters to get the text inside
one that would supposedly give an ansi formated version of the message
and one that would supposedly give a plaintext formated version of the
message. They both returned the same string, though, which would either
be with ansi escape codes or plain text depending on the environment at
compile time.

This CL fixes that by having both messages, and letting the reporting
(i.e. whenever the message is read) decide which to use. That way we
can - for instance - report errors with color if the terminal supports
it correctly when reusing a dill (and reissuing problems, but where the
terminal support changes) and if printing the problem to an html <pre>
field (like observatory does).

It also cleans up two different implementations of whether we think
the terminal supports colors or not, by deleting one of them.

This is the second try. Patchset #1 is the original.
Patchset #2(and possibly beyond) is the changes.

TEST=Existing test suites.

Jens Johansen e2b6208871 [CFE] Shard front-end try bots better
This CL shards the CFE try bot tests better.
* co19_2 runs was previously made faster, so using 10 shards on that is
  way too much.
* sdk_test runs was previously made faster, so using 5 shard on that is
  way too much.
* unit_tests was taking ~10 minutes and wasn't sharded. This CL shards
  it. Note that this sharding is semi-complicated because a few tests
  use git which is not usable on shard-runs. To overcome this a previous
  CL renamed the tests that use git and here the sharded runs only run
  the tests that doesn't require git. Then the "main bot" runs the tests
  that require git.
* unit tests suites was taking ~12 minutes and wasn't sharded. This CL
  shards it. Note that this sharding is semi-complicated because a few
  of the suites use git which is not usable on shard-runs. Also a single
  suite uses many more files that it is reasonable to include in the
  fileset for the shards. In both cases these are run on the "main bot"
  instead. The suit runnier was already "threaded", but simply launched
  all threads (say around 20 or something like that) at the same time.
  That's not ideal if having, say, 8 cores to work with (which is what
  the bots seem to have) - or 12 (which is what my computer has).
  Now only 'cores - 1' "threads" are run at any one time, and most
  "sub-suites" are sharded, so that if one finishes early that core
  can start another "sub-suite" - hopefully utilizing more of the
  resources avaiable on the computer running it.

In total - in my 'benchmarks' (i.e. try bot runs) - the
front-end-linux-release-x64-try bot previously rook around 35 minutes
to complete, and with these changes it takes around 15 minutes to
complete. The biggest entry in the timeline is now building dart which
takes almost half that time. It does so with fewer shards than before,
but each might be utilized for longer.

Jens Johansen 6d7c92f016 [CFE] Add "strong" tests of the constant evaluator
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.

Jens Johansen ce5556ab36 [kernel] Load classes lazily
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%.

Map with key 'value' has different values (tag 1, likely 'Something<1>')
Map with key 'function' has different values (tag 6, likely 'Procedure')
Lists have different values at index 0
Map with key 'items' has different values
Map with key 'procedures' has different values (tag 2, likely 'Class')
Lists have different values at index 6
Map with key 'items' has different values
Map with key 'classes' has different values
Lists have different values at index 458
Map with key 'libraries' has different values

Which should be read bottom up as something like
Component -> the 458th library -> the 6th class ->
    the 0th procedure -> function -> returnType (a InterfaceType) ->
    0th type argument (a TypeParameterType) ->
    nullability has value 2 in one input and 3 in the other.
