Previously all arrays were excluded from WB elimination pass
to avoid invariant restoration code creating excessive work
for the GC and to avoid dealing with card marking in the
invariant restoration code.
It seems reasonable to enable this for small arrays of up to 8
elements. The cut of point of 8 elements was chosen based on the
cut of point for literal<N> specialisations provided by the
core library for creating small literal arrays.

This CL implements `Finalizable` by means of a CFE transform.
The transform is implemented in the existing FFI transform to avoid the
overhead of traversing the AST an extra time. The FFI transform slows
down ~15-30% on Flutter Gallery. For more info see the design doc.

In general any async function can return X or Future<X>. Though the
future implementation has to do different things depending on which case
we're in. It does so by using a `<obj> is Future<T>` test. This test is very
expensive if many different classes flow into `<obj>`.
Though most functions do not return `Future` objects from async
functions. We can determine that statically by looking if any returned
expression could be a future. If not, we can bypass the `is Future<T>`
test entirely.

In general this moves in the direction of dealing more with Identifier instances instead of TypeAnnotation instances.
This ended up being a larger refactor than I had hoped, but at a high level it does the following:
- Adds the TypeAnnotationCode/NamedTypeAnnotationCode/FunctionTypeAnnotationCode classes
- Change the TypeResolver api to have a single 'resolve' method, which takes a TypeAnnotationCode argument
- Makes ParameterCode/TypeParameterCode take more structured arguments
- Update the CFE code to be able to resolve NamedTypeAnnotationCode instances instead of TypeAnnotation instances
- Also deletes some unnecessary Code classes.
Note that supporting FunctionTypeAnnotationCode instances looks like it will be some more work in the CFE.

The java generation for type `(string|Null)[]` was creating `@return one of <code>List<String></code> or <code>ElementList<Null></code>`
see example:
```
@SuppressWarnings({"WeakerAccess", "unused"})
public class UriList extends Response {
public UriList(JsonObject json) {
super(json);
}
/**
* A list of URIs.
*
* @return one of <code>List<String></code> or <code>ElementList<Null></code>
*/
public Object getUris() {
final JsonObject elem = (JsonObject)json.get("uris");
if (elem == null) return null;
if (elem.get("type").getAsString().equals("String")) return new String(elem);
if (elem.get("type").getAsString().equals("Null")) return new Null(elem);
return null;
}
```
My change is the simplest thing I could think of, just making the return type `List<String>` instead and allowing some of the elements to be null. But I'm happy to implement something else if someone has a suggestion for a better type (along with how to get the generate code to produce it)

Currently we have to do a runtime `as FutureOr<T>` check for the
parameter to `_Future<T>.asyncComplete(FutureOr<T> value)`. Although
needed for general cases, for the particular usage in the VM's
async/await transformer, we know that the test is going to suceed.
This CL adds two VM-specific methods on `_Future` that take `dynamic`
and downcast via `unsafeCast<>()` to avoid this rather large runtime
type checking overhead.

Change after revert: Replace the
assert(value is T || value is Future<T>);
with
assert((value as FutureOr<T>) == value);
The former doesn't allow `null` while the ladder might (depending
on nullability of `T`).

Currently:
* "ddc nnbd weak tests" is split into 5 shards.
* "ddc nnbd weak co19 tests" is split into 2 shards.
* "ddc nnbd strong tests" is not spit into shards.
* "ddc nnbd strong co19 tests" is not spit into shards.
From a recent run taking a total of 45 minutes the timings
were like this:
```
ddc nnbd weak tests shard 1: 02:57
ddc nnbd weak tests shard 2: 01:56
ddc nnbd weak tests shard 3: 02:16
ddc nnbd weak tests shard 4: 01:49
ddc nnbd weak tests shard 5: 02:31
```
(i.e. a combined total time of 11:39 if run one after another)
```
ddc nnbd weak co19 tests shard 1: 08:45
ddc nnbd weak co19 tests shard 2: 09:48
```
(i.e. a combined total time of 18:33 if run one after another)
```
ddc nnbd strong tests: 09:51
```
```
ddc nnbd strong co19 tests: 20:44
```
Here I try to change the sharding "robin hood style" so that
"ddc nnbd weak tests shard" which seems pretty fast gets fewer,
but "ddc nnbd strong co19 tests" gets sharded.
Hopefully the result will be something like
ddc nnbd weak tests shard 1: 06:00
ddc nnbd weak tests shard 2: 06:00
ddc nnbd weak co19 tests shard 1: 09:00
ddc nnbd weak co19 tests shard 2: 09:00
ddc nnbd strong co19 tests shard 1: 7:00
ddc nnbd strong co19 tests shard 2: 7:00
ddc nnbd strong co19 tests shard 3: 7:00
ddc nnbd strong tests: 10:00
Which - with the same number of shards used - would hopefully cut off
~20 minutes (as the shards run concurrently)
Update: Total runtime was ~21 minutes, and runtimes seems pretty
agreeing with the expected.

The `_FutureListener.callback` field is used for multiple purposes
(possibly to save memory by avoiding additional fields) so it cannot
have a specific function type.
This causes the `Function?` typed `_FutureListener.callback` field to be
casted to proper function types such as `T Function(S)`.
=> Those runtime type checks are very expensive.
To avoid introducing more fields we use an `unsafeCast<T>()` for those
casts, since the implementation guarantees they are going to suceed.

This will set benchmarking to true, do 3 iterations and eventually print
the benchmarking data as json. That can then be pasted into the attempted
visualizer.
This is a first stab, and might be replaced by something else down the line.
