Add the -mno-red-zone for gcc on x64. Since the GNU calling convention of x64 defines the 128bytes red zone beyond the stack point could not be modified by interrupt or exception handler, and Edk prime assumes all data beyond stack point should be volatile, if not add the option, the interrupt or exception handler may corrupt the red zone, which may be used as temporary storage.
