	* gas/i386/i386.exp: Run segment and inval-seg for i386. Run
	x86-64-segment and x86-64-inval-seg for x86-64.

	* gas/i386/intel.d: Expect movw for moving between memory and
	segment register.
	* gas/i386/naked.d: Likewise.
	* gas/i386/opcode.d: Likewise.
	* gas/i386/x86-64-opcode.d: Likewise.

	* gas/i386/opcode.s: Use movw for moving between memory and
	segment register.
	* gas/i386/x86-64-opcode.s: Likewise.

	* : Likewise.

	* i386.h (i386_optab): Don't allow the `l' suffix for moving
	moving between memory and segment register. Allow movq for
	moving between general-purpose register and segment register.
