This CL:
- Fixes https://github.com/dart-lang/sdk/issues/43987 (an exception in custom formatting code)
- Restores (most of) debugger_test.dart to passing (which tests above)
- Fixes a type caching error also exposed by the above test
Note, this skips the golden file comparison. That appears to be very broken
(see comment).

This reverts commit 9dade7fd21.
With changes further in the relation chain, specifically around
making native null assertions tied to sound null-safety only,
the failure which caused the original revert should no longer occur.

The covariance optimization assumed that private members only occur
in the library in which they are private. This is not the case. The
CFE injects member signatures, forwarding stubs and noSuchMethod
forwarders for private members into other libraries.
This change takes that into account by only removing covariant bits
on members private to the enclosing library.
This hopefully a fix for https://github.com/flutter/flutter/issues/66122

- Fixes broken benchmarks in ddc because the benchmarks run in
d8 with the ddc module system can handle conflicting library
names more gracefully than es6.
- In the future we need to update the source of truth for
dart_library.js so we can keep the file in sync.
- Removes the ability for ddb to run with any precompiled sdk.js
from a dart installation. Now you must run a build first and
the sdk.js files from that build will be used. This means the
`--debug` flag no longer changes which sdk.js files are used.

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'.

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.

All of the backends (dart2js, DDC, VM) were checking if the invocation
name was tagged with "set:" and appending "=" to the name if so.
Instead, we can simply have the CFE perform this logic at the callsite.
Note that the name of the setter itself is still unchanged. Backends may
still need to generate the correct name themselves when handling NSMs
via code paths other than instantiateInvocation.
