This makes the DeoptimizeAll function O(n) instead of O(n^2) where n in the number of optimized functions.
Before this change, DeoptimizeAll iterated over the optimized function list and called DeoptimizingVisitor for each function. The visitor iterated over the optimized function list again to remove the functions that share the same optimized code.
This change partitions the optimized function list into one or more lists of related functions in one pass over the optimized function list.

Deoptimization support for accessors.

Highlights of this CL:
* Introduced a new opcode in the deoptimizer for a setter stub frame.
* Added a global setter stub for returning after deoptimizing a setter.
* We do not need special deopt support for getters, although the getter stub creates an internal frame. The normal machinery works just right for this case, although we generate a stack that can never occur during normal fullcode execution. If this hurts us one day, we can parameterize and reuse the setter deopt machinery.
