VM-internalize the default Map implementation.
...
Make the compact linked hash map, which is the default implementation for Map
(including map literals), a VM-internal class.
This makes it easy to have more efficient serialization of maps (although for
now, the implementation is straight-forward).
Refactor the compact hash class hierarchy to enable the VM-internal class and
the rest (also the Set classes) to share a maximal amount of code, by using
two different bases for implicit/explicit fields.
Remove existing proof-of-concept, C++-based internal VM-class.

Replaces LongJump with LongJumpScope.
...
LongJump required explicitly restoring the old
long jump base before function return. This was
sometimes forgotten, leading to crashes. This
change puts the base restoration into the
destructor so that it happens automatically on
return.

Introduce class TypeRef in the VM to fully support recursive types.
...
Fix issues 15244, 15148, 14869, 14000, and 13688 (was closed, but fragile).
Note that the current solution is not final as it may not be correct in more
complex cases not yet covered by language tests.
The final solution will require a 'trail' instead of a simple mark bit to
prevent operations involving recursive types to diverge.

Mark native functions when they are created.
...
Until now the parser marked native functions as native when parsing.
This may be too late for some functions. E.g. the native typed list
constructor may not be invoked because the intrinsic code is executed
instead (unless for example new-space allocation fails).
This causes missing type information when optimizing functions using
those recognized factory functions like Uint8List._new.

Do not eagerly finalize classes in CHA, instead regard unfinalized classes as ’non-existent’ and only invalidate optimized code at finalization of the class.
...
Rename FinalizePendingClasses to FinalizePendingClassInterfaces as the class finalization occurs lazily.
TODO: add dependency information to deoptimize/remove only relevant optimized code.
