This CL propagates types for simple variable declarations into analyzer ASTs.
Note that for a variable declaration like `int x` we need to store two
pieces of information: the element pointed to by `int`, and the type
of `x`. This CL handles the latter. The former will wait until we
have enough of the element model built that we have an element to
point to.

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.

In a future CL I'm going to start taking advantage of the fact that
these methods provide a fallback behavior when the listener doesn't
override a more specific method, so to avoid confusion I'm renaming
the methods to reflect that use case.

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.

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

This CL creates synthetic kernel objects for two additional
BodyBuilder corner cases:
- The synthetic "throw" expression created when code attempts to
construct an abstract class.
- The "throw" expression created when code attempts to assign to a
read-only expression.
With this change, we now create a KernelComplexAssignment object for
all assignments; this has allowed me to streamline the code for
creating assignments slightly.

* update test because fasta scanner correctly warns on 1.e+2
* fasta scanner correctly produces compile time error
see dartbug.com/28664
fix dartbug.com/28680
* update fasta AsciiControlCharacter error code
* enable fasta scanner in analyzer by default
