[PATCH] rs6000: Fix a mistake in cstore_si_as_di (PR68865, PR68879)

convert_move does not know how to zero-extend a constant integer to the target mode -- simply because it does not know the target mode. As a result, 32-bit SImode with the high bit set would be effectively sign- extended instead of zero-extended. This patch fixes it. Is this okay for trunk?
