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.

Deletes the outline stubber as it's not necessary on any backend.
DDC should compile the entire sources and outline dill in one step.
dart2wasm operates similarly, and so only needs the modular transformer.
dart2js moves the erasure to a global transform.
Also, this CL reverts now unnecessary plumbing that was needed for the
outline stubber.

Adds referenceFromIndex to outline transformations so that the eraser
can use it to find the reference for the stub if it was already created.
This is needed when the module where the stub exists is invalidated.
Since references in other modules should still be valid, we should
attempt to get that reference.

This CL changes the way dart: libraries are considered supported when
used in conditional imports or bool.fromEnvironment constant using
the "dart.library.*" values.
Library nodes now has an isUnsupported flag which is set according to
the "supported" property in the libraries specification. Furthermore
the Target now supplies a DartLibrarySupport interface that allows
targets to override whether dart: libraries are unsupported.
This allows the JIT/AOT to use the same platform file but still
consider dart:mirrors unsupported in AOT mode, and dart2js to consider
the internal library `dart:_dart2js_runtime_metrics` supported.
Furthermore, the internal handling is changed so that condition imports
and bool.fromEnvironments constants are computed through the same logic
for "dart.library.*" values, avoiding the need for passing these values
through the environment.

As a result, TFA converges much faster and AOT compilation time
improves.
RTA is less precise than TFA, so the set of allocated classes is
larger compared to the one calculated by TFA. However, it has only
marginal effect on the size of resulting AOT snapshots.

This CL adds a flag, `assume-initialize-from-dill-up-to-date`, to the
`frontend_server` which will skip the check and potential invalidation
of files from the dill we're initializing from.
Normally the sources included in the dill is used to figure out what
files that was used to produce the dill has changed and thus needs to
be invalidated after we've initialized from it. If we didn't do that
we'd be in a bad state where some changes would not be discovered.
In some circumstances, though, we might know that the sources haven't
changed and the check is thus not needed. This could for instance be
if we're initializing from a dill that was just build by another build
system.
