Reviewers: Michael Starzinger,
Message:
Submitted for an initial review round, ia32 and x64 support is fully
functional,
2 (hopefully tiny) things are still missing on ARM and MIPS.
Description:
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.
