    RISC-V: Add test for vec_duplicate + vrsub.vv combine case 1 with GR2VR 
cost 0
    
    Add asm dump check test for vec_duplicate + vrsub.vv combine to vrsub.vx.
    
    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
            for vrsub case 1 with GR2VR cost 0.
