    RISC-V: Add test for vec_duplicate + vsaddu.vv combine case 1 with GR2VR 
cost 0, 1 and 2
    
    Add asm dump check test for vec_duplicate + vsaddu.vv combine to
    vsaddu.vx, with the GR2VR cost is 0, 1 and 2.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/riscv/rvv/autovec/vx_vf/vx-4-u16.c: Add asm check
            for vsaddu.vx combine.
