amdgcn: silence warnings

Browse source 
The operands really should be VOIDmode, so the warnings are false.

gcc/ChangeLog:

	* config/gcn/gcn-valu.md
	(vec_extract<V_1REG:mode><V_1REG_ALT:mode>_nop): Mention "operands" in
	condition to silence the warnings.
	(vec_extract<V_2REG:mode><V_2REG_ALT:mode>_nop): Likewise.
	* config/gcn/gcn.md (*movti_insn): Likewise.
