Running a 64-bit kernel on a 64-bit CPU without an FPU would cause the emulator to run in 32-bit mode. The c0_Status.FR bit is wired to zero on systems without an FPU, so using that bit to decide how the emulator behaves doesn't allow for proper emulation on 64-bit FPU-less processors. Instead, we need to select the emulator mode based on the user-space ABI. Since the thread flag TIF_32BIT_REGS is used to set c0_Status.FR, we can just use it to decide if the emulator should be in 32-bit or 64-bit mode.
