    Original change's description:
    > [TurboFan] Fast path for JSAdd with BigInt feedback
    > 
    > This CL introduces the necessary infrastructure to generate speculative
    > BigInt operations in case of BigInt feedback. In particular, the JSAdd
    > operator is lowered to a speculative call to the  BigIntAdd builtin,
    > with a deopt bailout in case of exceptions or violated assumptions.
