i386.md (*movti_internal): Substitute Ye constraint with Yd constraint. 

* config/i386/i386.md (*movti_internal): Substitute Ye constraint
	with Yd constraint. Set "preferred_for_speed" attribute from
	TARGET_INTER_UNIT_MOVES_{FROM,TO}_VEC for alternatives
	with Yd constraint.
	(*movdi_internal): Ditto.
	(movti_interunit splitters): Remove
	TARGET_INTER_UNIT_MOVES_{FROM,TO}_VEC from insn condition.
	(movdi_interunit splitters): Ditto.
	* config/i386/constraints.md (Ye): Remove.
	(Yd): Do not depend on TARGET_INTER_UNIT_MOVES_{FROM,TO}_VEC.
