[Cui, Lili]

This patch is to clean reg class and base_reg for input output operand (%dx).

For special processing of input and output operands (%dx),
the state of some variables needs to be cleared.

gas/ChangeLog:

	* config/tc-i386.c (i386_att_operand): Clean reg class and
	i.base_reg for input output operand (%dx).
