Description:
Make FrameStates recursive (to be used for inlining).
- Changes FrameState node to require a 4th input
(use undefined as sentinel).
- Makes FrameStateDescriptor have a parent pointer.
- Instruction selection dumps dependencies of FrameState chain
into the instruction.
- Code generator builds the translation for rec. FrameStates.
(will require further integration tests)
