    RISC-V: Add test for vec_duplicate + vdiv.vv combine case 1 with GR2VR cost 0, 1 and 2
    
    Add asm dump check test for vec_duplicate + vdiv.vv combine to vdiv.vx,
    with the GR2VR cost is 0, 1 and 2.
    
    The below test suites are passed for this patch.
    * The rv64gcv fully regression test.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/riscv/rvv/autovec/vx_vf/vx-4-i16.c: Add asm check
            check for vdiv.vx combine.
