When mixin application is transformed, mixin is added to the end of
interfaces list. This may cause assertion failure if the same class
is used as mixin and mentioned among implemented interfaces.
This CL relaxes that assertion for mixins as this duplication is very
rare and seems harmless.
Note that it would not be valid to remove duplicated interface/mixin
from the list of interfaces, as it would break dart:mirrors in this case:
dart:mirrors needs to reflect duplicated interface/mixin both in
ClassMirror.superinterfaces (which is populated from the
list of interfaces without last element) and ClassMirror.mixin (the last
element in the list of interfaces).

Turn off concurrent marking during a reload as new instances could be allocated when loading a kernel file and this results in inconsistencies for the marking thread which is traversing the heap and expects to find instances only from the old set of classes.

CanonicalType is a leftover method/field from the time classes were keeping
track of their own canonical types and is still used for non-generic classes.
DeclarationType is more general and can be used where CanonicalType is used.
The field canonical_type_ is renamed to declaration_type_ and now caches the
DeclarationType.

In Dart2, mixin application classes are generated by kernel and type resolution
is performed by kernel. In Dart1, using the VM parser, these tasks were done
during class and type finalization.

This CL introduces, similar to RawClass::direct_subclasses_, a
RawClass::direct_implementors field which is kept up-to-date.
The generation of type testing stubs uses this cached
reverse-relationship information for faster cid-range calculation (time
spent in type testing stub generation is decreased by an order of
magnitude).
This CL also enable type testing stubs for any instantiated type.
This seems to improve
* analysis-server-cold-analysis by 6%
* analysis-server-warm-analysis by 11%
as well as other non-analysis benchmarks in JIT mode.

Previously there were places in the code where an API accepted a
`bool validate_frames` and call sites passed an enum value (which
implicitly got converted to a bool).
By changing the APIs to require an enum, the compiler will tell us if a
caller doesn't pass one.

Dart_LoadKernel is only used in Flutter engine and dart_runner, where it is always used as Dart_LoadKernel(Dart_ReadKernelBinary). These uses should be replaced with Dart_LoadScriptFromKernel.
Dart_LoadLibraryFromKernel is needed for loading split kernel files and implementing IsolateMirror.loadUri.
