The current
version is passing all the existing test + a bunch of new tests
(packaged in the change list, too).

The patch extends the SlotRef object to describe captured and duplicated
objects. Since the SlotRefs are not independent of each other anymore,
there is a new SlotRefValueBuilder class that stores the SlotRefs and
later materializes the objects from the SlotRefs.

Note that unlike the previous implementation of SlotRefs, we now build
the SlotRef entries for the entire frame, not just the particular
function.  This is because duplicate objects might refer to previous
captured objects (that might live inside other inlined function's part
of the frame).

We also need to store the materialized objects between other potential
invocations of the same arguments object so that we materialize each
captured object at most once.  The materialized objects of frames live
in the new MaterielizedObjectStore object (contained in Isolate),
indexed by the frame's FP address.  Each argument materialization (and
deoptimization) tries to lookup its captured objects in the store before
building new ones.  Deoptimization also removes the materialized objects
from the store. We also schedule a lazy deopt to be sure that we always
get rid of the materialized objects and that the optmized function
adopts the materialized objects (instead of happily computing with its
captured representations).

Concerns:

- Is the FP address the right key for a frame? (Note that deoptimizer's
representation of frame is different from the argument object
materializer's one - it is not easy to find common ground.)

- Performance is suboptimal in several places, but a quick local run of
benchmarks does not seem to show a perf hit. Examples of possible
improvements: smarter generation of SlotRefs (build other functions'
SlotRefs only for captured objects and only if necessary), smarter
lookup of stored materialized objects.

- Ideally, we would like to share the code for argument materialization
with deoptimizer's materializer.  However, the supporting data structures
(mainly the frame descriptor) are quite different in each case, so it
looks more like a separate project.

Thanks for any feedback.

Support loads from primitive values.
This also changes load computation to use HeapTypes rather than Maps.
TODO: move conversion between maps and heaptypes earlier in the process, already in the oracle.
