    Original change's description:
    > [turbofan] Rematerialize BigInt64 in deopt
    >
    > This CL introduces two MachineTypes - SignedBigInt64 and UnsignedBigInt64, which are represented as Word64 but will be rematerialized to BigInt in deoptimization. This will avoid unnecessary conversions for BigInt64s when they are passed to StateValues.
