rs6000: Remove useless operands[3]

As shown, three uses of operands[3] are totally useless, so
this patch is to remove them to avoid any confusion.

gcc/ChangeLog:

	* config/rs6000/rs6000.md (@ieee_128bit_vsx_neg<IEEE128>2): Remove
	the use of operands[3].
	(@ieee_128bit_vsx_neg<IEEE128>2): Likewise.
	(*ieee_128bit_vsx_nabs<mode>2): Likewise.
