This CL:
* introduces the Dart API to operate over libraries specifications and describes
the format we intend to use (see libraries_spec.dart)
* implements serialization/deserialization for this API
* switches over the front_end to use these APIs
* public options accept a URI to the JSON file and no longer
accept a `dartLibraries` map
* internal code uses the LibrariesSpecification API
* switches other dependencies on these APIs (resynthesizer_test and patch_sdk.dart)
This is the first step in migrating over to use the libraries.json format and
eventually remove the patched_sdk step. In particular, some of the next steps
include:
* add a build step to generate .json files from .yaml files
* add a libraries.yaml file for the sdk
* split the patched_sdk step in two:
* patching files
* generating .dill files
* add any missing support for patch-files in fasta
* finally remove the patching files step, and only have a build step for generating
.dill files

This reverts commit abf2d23af2.
Reason for revert:
- win build failed in patched_sdk (likely storing paths and not uris)
- dart2js bots failed (missing flag)
Will fix the issues and reland shortly.

We need this API to create a mock SDK in a way that makes
ProcessedOptions.validateOptions() to accept it - the SDK root
must exist.
Alternatively (or in addition to) we could make writeXYZ create parent
directories implicitly. So, to "create" a directory, you would need
to create a file in this directory.

Currently, fasta synthetically closes open braces until it finds
a match for the current closing brace. This works most of the time,
but provides less than optimal recovery in some common cases.
For example, given the following
class { foo()){print(a);} var a = 'hello'; }
the current brace recovery method fails to find any match for the
second closing parenthesis and synthetically closes the class
causing the rest of the file to be parsed as outside the class.
With this CL, fasta still synthetically closes open braces when it finds
a match for the current closing brace, but if there is no match, then
it just skips over the extra closer and continues. This approach dramatically
improves recovery in many cases where there is an extra closing parenthesis
or extra closing square bracket. In the example above, fasta parses
everything after the second closing parenthesis inside the class.

This technically steals a few tests from the previous batch that spans
corelib and language, but I wanted to start from the top of the language
tests.
Removed application_test and application_negative_test because they are
useless and the latter has never actually worked correctly since the day
it was transliterated from the long-defunct application file syntax.

Changes in this CL:
- Updated CompilerContext:
- it now contains a ProcessedOptions object
- it no longer depends on CompilerCommandLine/CommandLine
- it delegates to ProcessedOptions.report so all error reporting
goes to one single place.
- use "withContext" term instead of "withGlobalOptions" to be
more clear about the intent
- Changes in public API
- added more options that correspond to flags in command-line
fasta tools
- default onError is different: we now use the
command_line_reporting report, which prints and throws
on fatal messages, but doesn't throw eagerly on all messages
as before.
- introduced "printMessages" option: make it easy to have
both onError + command_line_reporting (kernel-service.dart
is the main use case at this time, other ideas welcome!)
- renamed CompilationError to CompilationMessage
- Other changes
- set exit code is done on report, not on format
- fixed corner cases not covered in previous CL
- error reporting with missing-main needs to happen with
a context
- missing error cases when inferring .packages and input
URIs are not file:* URIs
Ideas for follow up after this CL:
- combine ProcessedOptions and CompilerContext into a single class
(or extend one from the other)
- switch onError to a stream

Proper sequencing of _asyncStackTraceHelper in Kernel
This helper function was being called before its argument was
initialized so it was passing null. Instead, it should be called
after its argument is initialized.
Because the initialization happens in Kernel code, it is simplest to
insert the call explicitly in Kernel code as well as part of the async
transformation. This has the consequence that we now call the helper
function even when the flag causal_async_stacks is false.
Fixes issue #29771.
Fixes issue #30178
Fixes issue #30058

This code is no longer needed because we no longer run the front end
in "kompile" mode.
Also remove the old expectations files used by the "kompile" tests.
I will remove more code in future CLs.

This mode was needed in the early days of the front end when we were
contemplating the idea of building the analyzer AST representation of
code first, and then converting it to kernel. Now that we build
kernel directly, it is no longer needed.
Further CLs will follow to remove code that is no longer used after
this change.

This CL lays the groundwork for integrating the front end with
analyzer by creating a mechanism to copy resolution and type inference
information (produced by the front end's type inference engine) into
analyzer ASTs (produced by AstBuilder).
The general technique is to parse each function twice: once with
BodyBuilder as a listener and once with AstBuilder as a listener. The
BodyBuilder generates a kernel representation of the function, but
this isn't used; instead, type inference and resolution information is
captured using ResolutionStorer (which is a TypeInferenceListener).
Later, this information is applied to the analyzer AST generated by
AstBuilder using ResolutionApplier (which is an analyzer AST visitor).
At the moment the intermediate data exchanged between ResolutionStorer
and ResolutionApplier is simply a list of types (one for each
subexpression, in a post-order traversal of the program syntax). For
debugging and validation purposes, this is augmented with a list of
file offsets, so that if the ResolutionStorer and ResolutionApplier
get out of sync we can diagnose the problem easily.
In later CLs, more data will need to be exchanged between
ResolutionStorer and ResolutionApplier (e.g. a list of elements to
which identifiers are resolved).
This CL doesn't tackle the problem of translating between the kernel
and analyzer representation of types; for now we simply map each type
to `dynamic`. This is sufficient for early development, since it is
still enough to let us verify that ResolutionStorer and
ResolutionApplier stay in sync.

The test is currently skipped because of some flaky issue (issue #29819). I
noticed the test got broken while it's been disabled. This makes the test be in
working condition, even though it can't be enabled until we fix the underlying
flakiness in the VM.

Original CL had a bug that wasn't visible unless you delete your
out/ReleaseX64/patched_sdk folder.
Patchset #1 is the original CL, patchset #2 shows the fix.
This reverts commit 4aadfe09df.

Review-Url: https://codereview.chromium.org/2976543002 .
This CL tweaks the public APIs in package:front_end, and
starts using those APIs outside the package. For example, this
removes 9 uses of DillTarget, so it is not longer mentioned
outside pkg/front_end and the analyzer_target.
Actual changes:
- in package:front_end
* added kernel_generator_impl: new file contains code that
used to be in kernel_generator. Code has some modifications:
it uses a single canonical-root when loading summaries, and
it supports generating both outlines and kernel in one go.
* removed code that didn't belong here:
a. most of calculating deps for .GN moved to patch_sdk
b. vm-specific outcomes moved to kernel-service
* updated how `native` is implemented, so we can more easily
support dart2js and ddc
* updated how we check where `int`, `bool`, etc can be implemented.
* added support "hermetic mode" in modular builds
('chaseDependencies = false' option)
* moved `trim` step out of fasta, and for now call it only within
the public API. This is not yet exposed, and I stopped covering it in
most tests (now only covered in shaker tests). The plan is to add
tests for the public API covering this in the future.
* removed `uriToSource` when serializing outlines
* added unit tests for public APIs
- patch_sdk
* use the public API to craete platform.dill, outline.dill (now
500K insted of 3Mb because it excludes sources), and vmservice_io.dill
* moved here logic internal to .GN
- kernel service
* use the public API
* moved here logic that depends on VM internals (e.g. status enum,
compilation results)
- package:compiler
* use the public API in tools and unit tests
* simplified patched-sdk generation: no more extending fasta's internals
- package:kernel
* fix bug in deserialization: initializers and other lists were
overwritten accidentally with external definitions.
* updated unit tests, moved shared logic to frontend/src/fasta/testing
