The behavioral difference is that named and optional arguments are filled in
with their default values in the `Invocation` object passed to `noSuchMethod`.
On the implementation side we make NSM forwarders concrete and fill in their
bodies in the CFE. The custom (and somewhat hacky) VM support is no longer
needed, and Dart2JS can benefit from this implementation as well.
According to discussion on #33031 we will be able to re-land this soon without
breaking Mockito.
Prior failures on precompiler bots are fixed in Patchset 2.

This reverts commit 7d5025e814.
Reason for revert: <INSERT REASONING HERE>
Original change's description:
> Fix incorrect handling of NSM forwarders and pull all logic into CFE.
>
> The original implementation was designed around a shared misunderstanding
> of optional parameter handling in the spec. (which was also ambiguous about type parameters).
>
> The correct behavior for optional/type parameters is to fill them in with their default values/bounds.
> This behavior can be implemented without any backend support, as is done in this CL.

This CL introduces compileToKernel() function in package:vm/kernel_front_end
as the replacement for kernelForProgram() from package:front_end/kernel_generator.
The new function will be used to customize kernel Programs for VM need.
For example, it will perform additional AOT-specific global transformations.
In future, compileToKernel() will be used from Flutter and precompiler2.
Also, this CL cleans up Target.strongModeSdk as it is no longer used.

This CL adds handling of previously introduced 'strong-aot'
implementation (target-specific) option into VM target.
After this change, it will be possible to enable strong-mode
whole-program optimizations in Flutter (in addition to standalone VM).

This CL replaces outdated VmTarget and FlutterTarget with VmFastaTarget
and FlutterFastaTarget. 'Fasta' suffix is droped from target names.
The new FlutterTarget extends VmTarget, so they share more code.

Patchset #1 is the original CL, patchset #2 shows the fix.
This reverts commit 4aadfe09df.
BUG=
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

This transformation replaces the body of _getMainClosure in
dart:_builtin with `return main` for the script's main if there is one
and removes the body if there is no main.
Without this transformation fasta will compile `return null` and dartk
will compile `return throw new NoSuchMethodError...`. Both of these
patterns will be patched in the VM when dart:_builtin is compiled from
Kernel.

All generic methods are equipped with one extra named parameter for
passing type arguments as a list of type values.
Additinally, this change forces strong mode usage for 'dartk' in
'reified_dart'. Strong mode is required for loader to not strip away
type arguments from generic methods. In future, a command line argument
may be implemented for that (e.g. --generic-methods), if generic method
support will land before the strong mode.

This CL adds the work done at https://github.com/dart-lang/reify to SDK.
The commit that is used for the merge is
a2066a68374d49de92ff75f5e1ffc36335fd9451 (Nov 23, 2016). The code is
adjusted to respect the changes of the kernel package in SDK since that
commit.
The reify transformation is run by specifying 'vmreify' target to
'dartk'. The transformation requires its runtime library to present in
the program being transformed. The library is found in its default
location in SDK checkout if 'dartk' is run from its default location in
SDK checkout. To preserve the library in the output, TreeShaker is
disabled in 'vmreify' target.
The "golden" set of tests is also copied from 'dart-lang/reify'
repository, and the appropriate test suite is defined for it.
The bash script 'bin/reified_dart' from 'dart-lang/reify' is rewritten
as Dart script 'pkg/kernel/bin/reified_dart.dart'. It requires path to
'dartk' and path to SDK. Those are taken from their default locations in
SDK if 'reified_dart.dart' is run from its default location in SDK.
The added files were formatted using 'dartfmt' with default settings.
Additionally, the files were checked with 'dartanalyzer --strong'. The
necessary changes were made to fix the error messages. There are some
'hint' and 'error' messages left for some .dart files from the added
test cases, but they reflect intentional errors or conventions in those
files.

Target-specific modular transformations have to be able to cope with
external libraries. Target-specific global transformations should be
optimizations, and not required for correctness, since a simple linker
may choose not to perform them.
Make mixin resolution modular by making it fail when a mixed-in class
comes from an external library. (We cannot mix in such a class because
we do not necessarily have all class members.)
