Even when non-nullable is enabled by default, enabling the experiment
explicitly should result in the experiment release version (and not
the experiment enabled version) to be used for opting in.
For this change, the semantics of parseExperimentalFlags was change
to _not_ normalize the flags to a full mapping including default values.
For this reason all uses of such maps are renamed to
'explicitExperimentalFlags'.

Some of these synthetic files are created as packages but the
expression compiler wasn't designed to handle that information.
In the future we should support language versioning better in the
expression compiler or setup similar tests for opted in code since
in reality the language versioning might be handled by the dev
build system.

- use parameter types passed to IncrementalCompiler.compileExpression
for compilation of the synthetic function containing the expression
- updated expression compiler tests
Note: some expressions that previously compiled wouldn't now
Example:
** package:test/library.dart **
class TestLibraryClass {
final int field;
final int _field;
TestLibraryClass(this.field, this._field);
}
** main.dart **
import 'package:test/library.dart';
void main() {
var instance = TestLibraryClass(1, 2);
print('$instance'); // Breakpoint here
}
Expression:
`instance._field`
Previously, the incremental compiler would compile the expression
to kernel due to the type of instance being Dynamic. That compilation
result made it impossible for dartdevc to generate correct code due
to missing type information.
Now, the compilation will fail with "Getter isn't defined"
error. To properly evaluate private fields now, we would need
the CFE to support a special mode for expression compilation
where private fields from other libraries are allowed.

JS templates should always use their own source information. DDC
was incorrectly caching and reusing templates with the same source
information in various parts of the program. This lead to incorrect
source maps and in some cases compiler crashes when the source map
in a user application pointed to source location in the SDK.

- 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.
