Async transformation uses dynamic variables in few places (e.g.
for temporaries and for incomming arguments) - which creates
not strongly typed AST with method invocations having dynamic
receivers and non-null interface targets at the same time.
To maintain strong typedness of the AST we insert unsafeCast
when accessing the temporaries.

The BodyBuilder now operates on TypeBuilders instead of DartType.
This
* enables better error messages, and
* paves the way for removing the dependency on OutlineBuilder from BodyBuilder.

Previously we could get something like this:
```
regress_32660_test_06.dart:9:7: Context: 'foo' is defined here.
class I extends G implements H {
^^^
```
because a SyntheticForwarder was added with a file location of the
class.
It now instead goes to the forwarding stub target and says
```
regress_32660_test_06.dart:6:3: Context: 'foo' is defined here.
foo(int x, {int y}) => y;
^^^
```

Implement the feature spec for checking returns against inferred
function return types:
https://github.com/dart-lang/sdk/blob/master/docs/language/informal/invalid_returns.md
with the change that an invalid return without a subexpression is
a warning, not an error. This is because it is a warning in the
analyzer and it would be a breaking change to turn it into an
error.
The check for valid returns is moved to exactly where we handle
returns, rather than in ensureAssignable which is used as a
helper in a lot of places. A bug in type inference was fixed: we
would use `void` for the type of return without a subexpression
instead of `null`. To accommodate that we would use a
non-standard subtyping relation for returns. This could lead to
us inferring a return type of `void` in cases where we should
not.

E.g. `new Map<String>` is now reported as an error.
Note that this does not add a check for whether correct types are given,
so e.g.
```
class Foo<X extends num> {}
main() {
new Foo<String>();
}
```
is not caught by this fix.
Fixes#32972, #32281.

Bug: https://github.com/dart-lang/sdk/issues/33022
This commit adds an error when a final field is not initialized at all
(and there is at least one generative constructor). A later commit
will add an error for the case where a field is initialized by some,
but not all, generative constructors.
A number of classes in the Dart2js and DDC support libraries use
uninitialized final fields to indicate getters in the corresponding
native classes. This commit adds a temporary whitelist for the
affected files, which can be removed when the fields have been
replaced by external getters.
This is tracked by https://github.com/dart-lang/sdk/issues/33762

Before this CL, if initializing from a dill file containing a class,
say A, but it wasn't used, and then later using it as a type, say
'A a = new A()', the class hierarchy would complain about not knowing A.
This was caused by the class hierarchy initially being constructed using
the full component of the first compile (i.e. in the example above
without any usage of A and thus without including A), and subsequent
compiles telling the class hierarchy about new classes created in that
compile. The problem was, that if the class was loaded from a dill file
(in the example above 'A' was such a class) it would never be included
if not a part of the first full component.
This CL fixes it by changing the interface to the class hierarchys
`applyTreeChanges` function and letting the class hierarchy know about
libraries too: It will now basically just be given the full component
when asked to update, and just update with the libraries it doesn't
already know about. In the example above that would - once using 'A' -
include 'A'.
