srdjan@google.com caf04303f7 Deoptimization can occur at Dart calls (includes native calls to C) but not at runtime calls. This assumption (verified with Todd and Gilad) simplifies the implementation of lazy deoptimization considerably. 
Add flag --deoptimize-alot, which will lazily deoptimize all live optimized frames. Currently only the presence of deoptimization information is checked.

Add kDeoptAfter deoptimization point, which is the continuation for lazy deoptimization, after a call. Rename kDeopt to kDeoptBefore.

Removed a tests case that called into a native without properly setting up a Dart frame (Ok-d by Siva).

Native functions are not optimizable.

TODO: Split deoptimization information from DeoptimizationStubs. Check for redundant PcDescriptor information (what can be merged, especially at calls).

cshapiro@google.com 265e2306f5 Add a weak property type to the virtual machine. 
Weak properties are key-value pairs.  The liveness of the key determines
the liveness of the value.  If the key is reachable the value is traced.
However, if the key is unreachable, the value is subject to finalization.

At present, the sole finalization action is clearing the key and value
fields.  However, it is possible to extend this to invoking callbacks or
other techniques, as well as processing values in topological order.
