RISC-V: Add test for vec_duplicate + vwsubu.vv signed combine with GR2VR cost 0, 1 and 15

Browse Source 
Add asm dump check and run test for vec_duplicate + vwsubu.vv
combine to vwsubu.vx, with the GR2VR cost is 0, 2 and 15.

	* gcc.target/riscv/rvv/autovec/vx_vf/vx-1-u16.c: Add asm check
	for vwsubu.vx.
