Allocate contexts to hold captured variables. Rewrite captured variable
access to context access. Outside of a local function, this is a single
indirection through a named context. Inside a local function it requires
traversing (a statically known number of) parent links.

The analyzer keeps a separate AnalysisContext for the SDK, and the
options we set on our own context did not match those on the SDK,
mainly causing issues for strong mode.
Also, the BatchModeState is now used to share the Dart SDK, instead of
using a single instance held in a static variable.

Some backend targets require extra libraries that are not used
explicitly by a program (e.g., the Dart VM requires its bootstrap
libraries). Add a target-specific list of these libraries and ensure
that they are loaded when loading a program from Dart sources.

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.

- Rewrite all expressions in functions, not only expression-statements.
- Inject :await_ctx_var and :await_jump_var into the wrapper.
- Don't use transformed expression directly as part of completer.complete call.

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.
