    RISC-V: Add testcases for vec_duplicate + vadd.vv combine case 1 with GR2VR 
cost 1
    
    Add asm dump check and for vec_duplicate + vadd.vv combine case 1 to vadd.vx
    with the cost of GR2VR is 1.  The testcases is not that tidy according
    to the result, but we will continue tuning the cost model for this.
    
    The below test suites are passed for this patch.
    * The rv64gcv fully regression test.
