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.
