This is done through a synchronized cache between the server and client. When serializing a remote instance, if the server has already serialized that object then it will only send the ID in the future.
These caches currently only live as long as a single macro application in a given phase, but could live longer in the future. They do need to get reliably cleared out to avoid memory leaks though, and the shorter lifetime is easier to manage consistently.
This also allowed me to remove the specialized server/client modes (clients would always only send back IDs previously).

This entrypoint is practically unused. We normally use
`lib/src/dart2js.dart` instead.
Long ago it wasn't possible to launch a script from the `lib` folder
without running into import canonicalization issues. However, a few
years ago the VM and CFE now normalize the entrypoints. When we
invoke `pkg/compiler/lib/src/dart2js.dart` it gets treataed as
`package:compiler/src/dart2js.dart`. As a result, we really no
longer had a need to have a separate entrypoint in the `bin` folder
that reexports the other entrypoint.
The only remaining references to this file were from documentation
and a couple unit tests. This CL updates those remaining uses.

The VM can read native asset mappings from kernel.
Previous CLs already added support to embed native asset mappings for
one-shot compilation.
This CL adds support for adding native assets mappings to kernel files
created by the frontend_server with the incremental compiler.
The frontend_server accepts a `--native-assets=<uri>` at startup and
accepts a `native-assets <uri>` message on stdin as compilation
command.
The frontend_server caches the compiled native assets library.
When a `reset` command is sent to request a full dill from the
incremental compiler, the native assets mapping is taken from the
cache and added to the final dill file.
Split of DartSDK & flutter_tools prototype to land separately.

* Add an `targetOS` argument to `pkg/vm`'s `compileToKernel`,

* Add a new `--target-os` command line argument for all binaries
that use `compileToKernel` for clients to provide the target
operating system, if known.
* Add a new`"vm:platform:const"` annotation to certain field and
getters in the Platform class.
This annotation is used to annotate static getters and fields with
initializers where the getter body or field initializer must evaluate
to a constant value if the target operating system is known. This
annotation may be used outside the Platform class and in user code.
For example, this annotation can be used on a static `String` field
that is initialized with one value if `Platform.isWindows` is true
and to a different value if `Platform.isWindows` is false.
Note: If the const functions experimental flag is disabled, then
any annotated static methods can only contain a single expression
whose value is returned. If it is enabled, then the static method
is evaluated as if it is a const function with the special
handling of annotated static fields and getters above.
* Create a VM constant evaluator that evaluates uses of static getters
and fields marked with the above annotations when a target operating
system is provided.
* Use the new VM constant evaluator in the unreachable code elimination
transformer.

When launched as a snapshot, the initial compile is slower than the existing pub approach because of a process start time of around 500 ms. When launched as a compiled executable, initial compile times are the same as the existing pub approach. Once launched, experimental results show times to produce a kernel file of at worst 1.5-2x faster than pub's solution and at best 10x faster than pub's solution. The typical workflow of making changes and recompiling results in an average of a 5x speedup with respect to pub's implementation.
Because compiler instances use a lot of memory, there is a limit on the number of active compilers that the resident server will keep alive, and will actively bring instances down when this limit is exceeded. If the user was previously compiling a given project during the lifespan of a ResidentFrontendServer and its compiler is taken down between requests, a new compiler instance will be allocated for the request. Performance is still between 1.5x-5x faster for this case when compared to pub's compile times.
