i386.md (all uses of ext_register_operand): Make sure they are VOIDmode; replace all uses outside zero_extend.

	* i386.md (all uses of ext_register_operand): Make sure they are
	VOIDmode; replace all uses outside zero_extend.
	(and?i splitters): Use ext_register_operands.
	(test?i peep2): Remove ignored constraints.
	* i386.c (ext_register_operand): Check that operand is
	eighter pseudo or hard or 'Q' register.
