- Move expression evaluation to ddc in preparation for google3
- Added server to ddc to handle update and compileExpression requests
- Added tests
- Added 'experimental-output-compiled-kernel' option to ddc to generate
full kernel files only for compiled libraries, and store with
'.full.dill' extension
- Added AssetFileSystem to communicate to the asset server in the
debugger
- Made expression_compiler_worker work with full kernel files,
so removed invalidation of current file to improve performance
- Made expression_compiler_worker reuse already loaded imports
to avoid reading them from source in the incremental compiler
- Updated tests to work with DDC (for simulating webdev)
- Disabled tests that work with bazel kernel worker for now
as it does not generate full dill files yet
- Addressed code review comments from the prototype version:
https://dart-review.googlesource.com/c/sdk/+/157005
Details:
Currently, in flutter tools, expression evaluation is supported via
expression compilation, which is done by the incremental compiler in
the frontend server. The same incremental compiler is used for initial
application compilation, incremental code compilation for hot reload,
and any number of expression compilation requests.
In google3, the apps are typically too large to be compiled as a whole
in memory by the frontend server. Build in google3 is currently done by
blaze, as a distributed build using a task dependency graph. Build tasks
output kernel outline files as an interface between components produced
by individual tasks.
We are proposing an implementation of the expression compilation in
google3 that is taking advantage of full kernel files produced by the
build (supporting build changes to follow). This change introduces a
small server based on dev_compiler, which can handle following requests:
- update: load full kernel for given modules (done on app start)
- compileExpression: compile expression in a given library and module
(done when paused on a breakpoint)
Expression compilation uses previously loaded kernel files for the
application component and its dependencies to compile an expression.

This should enable strong mode tests to be fully NNBD opted in. At the
same time, legacy tests when run with the experiment off should
hopefully be able to still consume these libraries because they don't
actually use any NNBD features.
To do this, I changed the script that generates the SDK repo's package
config to not put in a language version for any package whose pubspec
has no SDK version. According to language versioning, that means the
package should be considered to be at the "current" version of the SDK
running the code.
In NNBD, that's opted in. With the experiment off, that is (presumably)
"opted out" in the sense that NNBD doesn't exist.
In order to *not* opt in some of the other packages that currently
lack SDK constraints, I put those in and pinned them to "^2.7.0" which
was what the package config script used to implicitly fill in for them.
I see a bunch of other changes in the generated package config too. The
update script probably hasn't been run in a while.

Converts `package:` import uris into `/packages/` modules.
Also renames the output modules to append `.lib.js` instead of just `.js`. This allows us to distinguish between modules and applications based on extension.
Updates DDC source map code to be able to convert absolute file uris in sources so that they are relative to the source map.

Adds support to the frontend server for producing javascript when
compiling with a target model of dartdevc. This uses the ProgramCompiler
and associated types from the dev_compiler package to output the kernel
AST into a "bundle" format.
dev_compiler:
* Exposes additional types needed for JavaScript compilation.
* Allows overriding CoreTypes instead of forcing it to be created from
Component. This is require to support compilation of the
partial Components created by the incremental compiler.
* provides extraIndexedLibraries in Target class so the CoreTypes produced by the incremental compiler have indexed them.
frontend_server:
* When the target model is dartdev, JavaScript is output instead of
kernel. For each Component we compile, we first compute the strongly
connected components and produce a List of new Components to interop
with the dev compiler. The file uri is used as module name.

To support JavaScript compilation, the frontend_server will require a dependency on the dev_compiler. To avoid conflating this with the vm specific functionality, the frontend server will be split from its current location.
This change will require a small corresponding update in flutter/engine, documented in the patches directory
