Qifan Pan 80fb281561 [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.
