The bailout process is modified to use bailout stub information to rebuild the stack one frame at a time instead of the existing bulk copy. - The bailout tail uses the bailout stub information to setup the bailout registers, copy contents of frames (besides the return address) and jumps to the appropriate bailout stub. - The bailout stub is setup so that simply calling back into the bailout tail materializes the expected return address - and the bailout tail can continue with the next frame.
