    RISC-V: Separate the test running of rvv vx_vf
    
    The default test running in rvv.exp takes the -fno-vect-cost-model
    for most of these options.  It is not that suitable as the vx_vf
    test depends on the cost-model.  Thus, separate the vx_vf test
    cases without -fno-vect-cost-model in another options.
    
    The below test suites are passed for this patch.
    * The rv64gcv fully regression test.

            * gcc.target/riscv/rvv/rvv.exp: Separate test running of
            rvv vx_vf.
