* Identify heap numbers that contain non-Smi int32s and do bit ops on them without calling the fp hardware or emulation. * Identify results that are non-Smi int32s and write them into heap numbers without calling the fp hardware or emulation. * Do unary minus on heap numbers without going into the runtime system. * On add, sub and mul if we have both Smi and heapnumber inputs to the same operation then convert the Smi to a double and do the op without going into runtime system. This also applies if we have two Smi inputs but the result is not Smi.
