Calls are now printed as follows:
Dynamic calls: receiver.name
Interface calls: receiver.{target}
Direct calls: receiver.{=target}
Dynamic super calls: super.name
Super interfaces calls: super.{target}

This makes super calls name-based (no target) and add direct calls with
both receiver and explicit target.
Super call resolution translates the name-based super calls into direct
calls after they have been cloned into the mixin application.
For JS backends, it should suffice to clone mixed-in methods that
contain super calls, but that transformation is not part of this CL.
This also adds a --target option to dartk designating the target to
which the kernel IR should be specialized. The new transformation
is run when --target=vm.

We need the ability to efficiently transform a mixin application class
into a regular class, and the separation was obstructing it. It also
simplifies the IR a bit, although it no longer enforces the invariant
that mixin applications cannot contain fields and procedures.
The binary format is unchanged, so the separation still shows up in
there. This ensures the CL can land without any changes to the SDK.

This adds a notion of bitmasks to the constraint system,
which will be propagated by the solver, and joined using
bitwise OR. The solver does not care what the bits mean.
These bits propagate nullability and other values that we
care to preserve when a good base class could not be found.
This also adds an interface in front of type propagation
that exposes the inferred types in an accessible manner.

This transformer is responsible for lifting subexpression into temporary variables preserved across yield points.
To maintain AST validity I introduced an expression that can contain a block of statements inside called BlockExpression.

LocalInitializer lets us to bind temporaries to variables in the
initializer list. We use it to ensure the arguments to super() are
evaluated at the right time.
accessors.dart and the new file super_calls.dart have been moved into
a folder "frontend" for frontend helpers that operate on Kernel IR.

This should help reviewers see how a change in type propagation affects
the current output.
There are currently only 3 tests with gold files. We can add more tests
ongoing as more features are implemented.
The expected outputs contains a lot of wrong types because the backing
type propagation is not complete.
