This changes the CFE expectation test suites to use unsound null safety
as default to avoid passing --enable-experiments=no-non-nullable to opt
out old test folders.
This change removes most test folders from the 'strong' tester, since
this now only supports sound null safety, which requires all libraries
to be opted in. Instead, the 'weak' tester now runs all test folders.
Additionally the 'outline' tester is changed to use unsound null safety
so that it call be used on all test folders.
The 'fast_strong' tester is removed since it should just be run locally
and it can be run by passing an option to the other testers.
References to non-existing 'shaker' folder has been removed from
testing.json.

Changes fields to be either mutable or immutable by construction.
This ensure that we don't create setter references for fields that
cannot be assigned to and is a prerequisite for replacing @fields/
@fields= canonical names with @getters/@setters.
TEST=existing expectation tests and verification

This CL adds stub for each concrete mixed in member into mixin
applications. The body of the stub calls the original member via
a super call.
This addition means that resolution of super access now use the
stub and not the original declaration as the target, which means
that it will be correct even when mixed in members are cloned. For
this reason, dart2js no longer needs to perform its own super
member resolution.
When a super call targets a mixin super stub (after cloning) it
can be optimized away by redirecting the call to the `stubTarget`
of the call. This optimization is performed in dart2js.
Since dart2js now uses the correct super target, its runtime
mixin application needs to avoid overriding members already
declared in the mixin application. These members are the
forwarding super stubs which ensure that correct runtime types
when members with covariant parameters are implemented.

DirectPropertyGet is a statically bound instance access used in the
VM mixin tranformation to encode fully resolved super access. The
access to `this.name` generated in `toString` of an enum is _not_
a statically bound instance access but just a regular instance access
whose runtime target happens to be known statically because the code
is generated. In JavaScript backend a statically bound instance access
requires a unique getter to avoid the dynamic lookup, and therefore,
though using DirectPropertyGet is an optimization
to the VM, it would be a regression to the JavaScript backends if
they didn't handle DirectPropertyGet as a PropertyGet.
This CL removes the misuse and thus enables JavaScript backends to
handle DirectPropertyGet with the intended semantics.

This CL basically change two things about the sorting:
* Entities are not sorted according to metadata. Metadata just follows
along. Before "@a class B {}" would come before "class A {}" because
"@" comes before "c". Now "class A {}" comes first because "A" < "B".
* Sorting happens on a token level, i.e. "F<int>" will now come before
"F2<int>" because "F" < "F2" whereas before it was the other way
around because "F2" < "F<" (because "2" < "<").
None of it really matters as long as sorting is done the same way when
comparing the outlines.
Doing it this way makes it faster and actually brings the runtime
(in benchmarks) less than the old (now deleted) textual outline.

Before this CL the textual outline didn't know about named mixin
applications which caused it to insert "fences", i.e. splaces it
wouldn't sort across.
So for instance
class E {}
class D {}
class C<T> = Object with A<Function(T)>;
class B {}
class A {}
would not be sorted fully because class C is a named mixin application,
something it didn't know about, and it would only allow stuff on either
side to be sorted. So the sorted output would have been
class D {}
class E {}
class C<T> = Object with A<Function(T)>;
class A {}
class B {}
With this change it knows about it and the output would now thus be
class A {}
class B {}
class C<T> = Object with A<Function(T)>;
class D {}
class E {}

E.g. before this change a procedure output would have been
foo() { }
now instead it becomes
foo() {}
this matches what the formatter does.

Add a kernel transformation which removes redundant casts and reduces
some casts to null checks. This transformation assumes that type
system is sound and subtyping relation is transitive. So in NNBD weak
mode this transformation is always correct. In NNBD strong mode
this transformation is correct only if opted-out libraries are not
allowed.
The following patterns are handled:
If S <: T (this includes S <: T? in weak mode)
S x; x as T => x
If S <: T? in strong mode
S x; x as T => (x == null) ? x as T : x
This kernel transformation is not specific to the VM and can be reused
by other back-ends such as dart2js and DDC.
