gen_snapshot can now consume a concatenated dill file.
Restrictions:
* The first dill file must be the main program.
* The subsequent dill files must only contain dummy libraries with
objects which are recognized classes in the VM and not treeshaken
in the main program.
This will enable compiling Dart AOT first, then using the tree-shaking
information to tree-shake native assets, and then embedding the native
assets mapping in the kernel file before running gen_snapshot.

Since we already cache instantiation of type argument vectors to avoid
runtime calls as long as the cache has room, remove the default
type arguments field from Closure objects. Instead, just perform any
needed instantiation when the default type arguments are needed
using the instantiator and parent function type arguments stored
in the closure.
Also rename DefaultTypeArgumentsKind to InstantiationMode and
generalize the calculations to determine how to instantiate default
type arguments to an operation that can be performed on type arguments
in general.

Previously, the default type arguments for closure functions were
instantiated in the same way as other types of functions, where the
instantiator and function type arguments of the call were used. However,
the defaults for closure functions should be instantiated with the
instantiator and parent function type arguments stored within the
closure itself.
Since the instantiation of the default type arguments only depends on
the instantiator and parent function type arguments, which are shared
between partial instantiations of the same generic closure, the VM
performs this instantiation once at closure creation and caches it in
the closure object, so it can be retrieved when the default type
arguments are needed and copied to new partial instantiations of the
same closure without need for recalculation.
As a side effect, this should speed up dynamic invocation of generic
closures, since the invoke field dispatcher that implements them
previously performed this instantiation when needed on every invocation,
but now it just retrieves the cached version instead.

This CL fixes AOT failures that happened after [0] landed. That code
removed lookup code for the `future_class()` in the
`ObjectStore::LazyInit*()` methods and replaced it with an assert instead.
The change was correct, since the lazy members should be initialized
on-demand - after the core, non-lazy members.
=> Though this seemed to not be the case in AOT, which hit the assert.
The reason [0] only caused failures in AOT is because in JIT the VM is
bootstrapped only from the vm_platform.dill file and as a secondary
embedder call the application.dill file is loaded.
Yet in AOT we have a combined full_application.dill which will all be
loaded during bootstrapping. That has caused the application to be
loaded before `ObjectStore::InitKnownObjects()` was invoked.
The initialization of [ObjectStore] which contains common core library
classes/functions/fields should happen before we use the kernel loader
to load user classes (since general kernel loading depends on the
[ObjectStore] being populated).
This also ensures that `ObjectStore::InitKnownObjects()` will be called
before `ObjectStore::LazyInit*()` - since they depend on the former having
run (e.g. that the non-lazy `future_class()` member of `ObjectStore`
was set).

Previously, we were crashing when trying to report a compile-time

That happened because we didn't have LongJumpScope set up.
This change sets up LongJumpScope and makes sure compile-time
errors during kernel loading can be reported and propagated up.
This also removes the need to use FATAL error when detecting
a dill file which is incompatible to the current runtime mode,
so we can use less severe compile-time error for that.

Previously, core snapshot was generated from AST
(because --enable-interpreter/--use-bytecode-compiler was not specified
when building core snapshot).
As the result, CL
https://dart.googlesource.com/sdk/+/da8cb470cc94830a98d49532e8d5d1a5b3d80f8b
which declared libraries in bytecode also removed bytecode entirely from
core snapshot in Dart SDK.
This CL enables bytecode by default if --bytecode argument is
specified for gn.py. This enables JIT compiler from bytecode
(interpreter is still disabled by default but can be enabled
using --enable-interpreter). Core snapshot and other
snapshots now have bytecode.
This change revealed a bunch of bugs which are fixed in this CL:
* _Closure fields were treated as unboxing candidates which triggered
assertion in LoadFieldTOS in interpreter.
* Several places should load class declarations if they are not loaded yet.
* Canonicalization of TypeRef objects which are not fully initialized
may cause duplicate entries in the hash table of canonical
TypeArguments. This triggers assertions when hash table is rehashed.
The solution is to avoid canonicalization of non-root recursive types
and recursive type arguments. Also, TypeRef::Canonicalize and
TypeRef::Hash are reverted to assert and work only if type was set.
* Native wrapper classes are eagerly stamped as type-finalized
which caused assertion failures when reading their class declarations
from bytecode.
* When building flow graph for FFI trampolines kernel offset of library
(which is now declared in bytecode) was queried. Added special case
to Function::KernelDataProgramOffset().
* In interpreter-only mode with simulator (e.g. SIMARM64) if simulator
is not called before code is interrupted with stack overflow check,
simulator returns get_sp() = 0, which was treated as stack overflow.
* test standalone_2/io/platform_resolved_executable_test.dart
spawns sub-process but it didn't pass VM options.
