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.
