Optimize vshuf{i,f}{32x4,64x2} ymm and vperm{i,f}128 ymm

Optimize vshuf{i,f}{32x4,64x2} ymm and vperm{i,f}128 ymm

vshuf{i,f}{32x4,64x2} ymm and vperm{i,f}128 ymm are 3 clk.
We can optimze them to vblend, vmovaps when there's no cross-lane.

gcc/ChangeLog:

	* config/i386/sse.md: Modify insn vperm{i,f}
	and vshuf{i,f}.
