Updates to kernel that sets more offsets (and introduces end offests
and 'debuggability') - but doesn't necessarily persist them,
i.e. the format doesn't change and no C++ changes are neccessary yet.
This is step #1 in introducing these things, next step(s) will be
persisting the new stuff and using it on the C++ side.

This is the result of:
- taking the diff of the branch closure_conversion to master in the kernel
repository
- updating the file paths
- applying the diff to the Dart SDK
- fixing conflicts between the changes to pkg/kernel in the Dart SDK and the master branch in the kernel repository

Previously, the type of a conditional expression could be omitted if
one of the arms was just a null literal. This was meant to simplify
translation into kernel, but wasn't really worth it in terms of
complexity, and it does not work well for types that carry nullability
information.

The interface target can now be stored on PropertyGet, PropertySet, and
MethodInvocation If set, we know the concrete target overrides or
implements that member.
All expressions have a method getStaticType for computing its type,
which relies on interface targets for the expressions that have one.
Expressions whose type is a least upper bound have the type stored
explicitly, so the definition of least upper bounds is contained only
in the frontend.
This is a work in progress towards strong mode support, it is still
not complete.
Still missing in the frontend:
- checks from implicit downcasts
- parameter checks from covariant override or covariant generics
Implemented but not part of this CL:
- subtype tests
- IR type checker (for debugging)

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.

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.
