Regressions in tests:
1) Test language_2/type_alias_equality_test/04 fails similarly to default mode, as VM
does not implement comparison of function types according to the specification.
Previously this test was passing as function types were canonicalized in bytecode,
which was not always correct. This CL fixes the problem with canonicalization of
function types in bytecode and the test starts failing again.
2) Tests standalone_2/entrypoints_verification_test, standalone_2/io/test_extension_test,
standalone_2/io/test_extension_fail_test fail as native extensions are not supported
in bytecode yet. These tests start passing after df5e7aac17,
which switched bytecode tests to kernel service (on x64), because kernel service doesn't
drop ASTs. This CL switches from reading AST library declarations to bytecode even if
AST is not removed, so tests fail again.

Before this CL we could both crash and add wrong metadata to "part"
nodes when a part defined other parts.
This CL fixes it by
a) Not resetting a counter so *every* part in a part will be out of
bounds when trying to reference it; and
b) Check if a part directive is in bounds and ignore it if it isn't
(an error should already have been issued).

During constant evaluation, unused arguments to a const constructor are
thrown away after evaluation, since their values do not affect the
resulting instance constant. If such an unused argument ends up
unevaluated, any errors that would arise in the final evaluation are
not reported.
This CL adds space in the Kernel AST for saving these unevaluated
expressions so they can be checked during final constant evaluation.
Even though this is an incompatible change, no update is needed to the
VM code (except for the version bump), since the VM does not support
InstanceCreation nodes in the first place.

Before this CL, whenever a dill library builder was asked to compute
the outline it would finalize its exports - even if it was already done.
This is not really a problem (it mostly puts stuff into maps --- doing
it again will just overwrite what's already there with the same thing
again), but when having many dill library builders, and asking them to
compute the outline again and again because we've added a few new ones
(e.g. via kernel worker) it adds up to a lot of wasted time.
This CL adds a boolean to the dill library builders to avoid re-doing
this already done work.
An internal benchmark via kernel worker of lots of outline
calculations in worker mode with reuse and the incremental compiler
(and lots of dill loaded dependencies) goes from ~149 seconds to
~143 seconds.

Prior to this CL, we would issue a warning whenever a CanonicalNameError
was encountered.
This is in principal a good thing, but because we currently have no way
to detect if the sdk we get is the one we expect
(by any other measure than when it issues a CanonicalNameError) we often
issue these warnings for no "real reason" whenever, for instance,
the flutter sdk changes.
This CL splits the CanonicalNameError in two such that errors with
references to the sdk ("dart:" libraries) issue CanonicalNameSdkError
instead, an we then handle that differently. Namely we silently ignore
the error (i.e. don't issue a warning) and just don't initialize from
dill.
This should remedy the situation and be strictly better than to always
swallow CanonicalNameErrors.

When the .packages file has changed we need to re-check all package-uris
to see if we need to invalidate the builders (if the file uri for a
package uri library (e.g. if the package was upgrade) has changed we
have to invalidate it).
This translation is semi-expensive though, so if we can avoid it that
would be a good thing.
This CL caches the "base URI" for packages from the previous run,
so we can start by comparing the base-URIs: If the base-uri for a
specific package hasn't changed, nor will the actual translation.
Only if the base uri has changed we do the actual translation,
and thus save many package-to-file-uri translations.
An internal benchmark via kernel worker of lots of outline
calculations in worker mode with reuse and the incremental compiler
(where the .packages file change every time and we have lots of
package-uri libraries) goes from ~185 seconds to ~162 seconds.
