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 canonicalization of symbols needs to take library privacy into
account. Since the Symbol class itself only has a [_name] field but does
not reference in which library the symbol came from, the [_name] must be
mangled.
Mangling is done by backends and so we make a new [SymbolConstant] which
the backends can desugar by doing appropriate mangling and construction
of a [Symbol] instance.

The VM debugger expects _completeOnAsyncReturn to be called when
returning from an async function for stepping out of the async function
to work.
This CL does just that.
Note that `_completeOnAsyncReturn` only exists in the VM, but as
the async transformation is only run for the VM target that shouldn't
be a problem.

Kernel mixin transformation desugars mixin applications into normal
classes. Mixed-in type is pulled into interfaces list.
However, dart:mirrors needs to know the original mixed-in type of
a mixin application.
This change solves this problem by propagating a 'isTransformedMixinApplication'
attribute of a class through kernel AST, kernel binary and VM objects
into dart:mirrors implementation.

To implement dart:mirrors correctly, a backend like the VM needs to
know that a class was originally a mixin application. Use the
`isSyntheticMixinImplementation` flag which was already there and
ignored by the VM.
Now the property is:
- if `isSyntheticMixinImplementation` is set on a class with a
mixed-in type, then it was originally an anonymous mixin application
- if `isSyntheticMixinImplementation` is set on a normal class then it
was originally a mixin application of some kind and the mixed-in
type can be found as the last impelemented type

The transformation worked as if there was never an await "to the
right" of the body of a let expression (i.e., an expression evaluated
after the let expression's body but before the value of the let
expression's body is used). This is obviously not right.

With this change debugger requests yield(await) positions from kernel builder so it can confirm which frame handles what exceptions.
This also renames ':completer' to ':async_completer' in constructed kernel, so it is compliant with what VM expects to see(and updates test expectations accordingly).
Further it fixes async stack navigation for sync-async that became default in dart vm since first version went for the review((uses `future` getter, rather than property).
It also makes `future` getter non-debuggable to allow stepping-out of async methods.
Make Handle zone-scoped. Clean up frame counter var name.

This CL:
* Removes unused functions in the ClassHierarchy
* Turns the data structures used in the ClassHierarchy upside down
(nodes have a lists of supers instead of lists of subs)
* Factors some things that needs the original list-of-subs into another
class that the user can ask the ClassHierarchy to compute if needed.
It appears that it isn't generally.
This is step #1 in turning the ClassHierarchy into an incremental
ClassHierarchy.
