This helper function was being called before its argument was
initialized so it was passing null. Instead, it should be called
after its argument is initialized.
Because the initialization happens in Kernel code, it is simplest to
insert the call explicitly in Kernel code as well as part of the async
transformation. This has the consequence that we now call the helper
function even when the flag causal_async_stacks is false.
Fixes#29771.

Closure conversion can now be run on a part of a program. It allows
using closure conversion in kernel-isolate. It comes at a cost of
temporarily sacrificing implementation of tear-offs via closures; VM
mechanism for tear-offs is used for now.

A smaller step this time - change only clients, but keep implementation
the same for now.
Not all patched SDKs have all classes and procedures, so I have to make
some them lazy. All of them could be done for consistency, but this
might slightly affect performance for often used dart:core classes.
Also it's a bit of mess now.
Maybe group these classes into logical structures, coreTypes.core.list,
coreTypes.async.future, coreTypes.async.futureMicrotask, etc. Something
like it was before this change, but fixed types and names instead of
more flexible (but in general slower) strings.

A new AST node 'ClosureCreation' is added. It takes a name of a
top-level function, a context, and a closure function type and creates a
closure of the given type. The effect of this closure invocation is the
same as of the invocation of the given top-level function with the
contexts as the first argument.
In order to use 'ClosureCreation', the closure conversion pass now
transforms closures into top-level functions, not closure classes. These
functions receive the context as the first argument.
The type of the expression represented by 'ClosureCreation' is its third
parameter. It its the responsibility of closure conversion pass to
create the correct types for 'ClosureCreation' nodes based on types of
closures transformed into top-level functions.

There are four operations that work on Vectors: Vector creation, looking
up an item in a Vector, assigning a value to an item in a Vector, and
copying a Vector. The first three operations are allowed to only use
integer literals as number operands (length for Vector creation, index
for item lookup and assignment). Corresponding AST nodes are created for
these operations.
Vectors are used to represent contexts in Closure Conversion. The parent
context is stored as item 0 in its children contexts. The "golden" tests
for this transformation are adjusted accordingly.
The support for Vectors is added to ast-to-text, ast-to-binary, and
binary-to-ast transformations.

All generic methods are equipped with one extra named parameter for
passing type arguments as a list of type values.
Additinally, this change forces strong mode usage for 'dartk' in
'reified_dart'. Strong mode is required for loader to not strip away
type arguments from generic methods. In future, a command line argument
may be implemented for that (e.g. --generic-methods), if generic method
support will land before the strong mode.

After 89b68e905b debugging of async
functions via kernel haven't worked.
Prior to this the dartAsyncMarker for e.g. a rewritte async function
would have been Sync, after it was Yielding.
This changes it back in the continuations rewriting cases.
An alternative fix would be to change
function.set_is_debuggable(
kernel_procedure->function()->dart_async_marker() == FunctionNode::kSync);
to something like
function.set_is_debuggable(
kernel_procedure->function()->dart_async_marker() == FunctionNode::kSync ||
kernel_procedure->function()->dart_async_marker() == FunctionNode::kYielding);
in the C++ code.

- Offsets on more stuff
- Status file for kernel
-> Testing with (before fasta)
```
python tools/test.py -mrelease -cdartk --no-tree-shake --no-dfe service
```
now shows everything as passing.
Reload stuff, and evaluation stuff (e.g.) has been disabled though.
- Lots of new service tests that tests what positions we stop at when
saying next.
As fasta has now landed debugging does not currently work, but this is still needed in order to both test better and allow for proper kernel debugging support.
