    Original change's description:
    > Changing the return address on the stack.
    > 
    > Rather than patching code, the deoptimizer now replaces the
    > return address in the frames with respective trampolines. 
    > This change required to change the way we search for Safepoint 
    > entries and for Exception Handlers. 
    > It's working in architectures: x64, ia32, arm, arm64 and mips. 
    > 
    > Bug: V8:6563
